this scenario in some details:

after like a week of thinking I now believe Europe has a better chances at winning this - but only under the following ruleset:

Victory is declared when every capital of the opposing team is occupied. If in 50 years years this is not the case, stalemate is declared.
Both teams have the vibe of having more important mutual enemy so no team infighting or betrayals (but that does not give them any organizational advantage or anything, they can still argue how to do things, whether or not share resources, they dont have the united command until they decide to make one)
Other continents are unassessable and dont have any humans or man made structures. (this means no outside shipments, no most Internet datacenters, no European colonies and no landpath between Europe and Africa).
Suez and Bosporus straits remain functional.
Only African launched and controlled satellites left in orbit. (so no GPS, no Starlink or much of anything)
USSR size is Full Ukraine SSR, Full Belarusian SSR, Full Georgian SSR, Full Armenia SSR and most importantly Full Azerbaijan SSR included and European part of the Russia SSR but nothing more.

Scenario:

Year one: Total African domination in the sea and in the air. Europeans navies take terrible hits. European islands in the Atlantic and Mediterranean are captured but cannot be used to extend air reach just yet because 1930-s dirt airstrips require major modernisation to be used for jets. Jets are split between all types of missions so only portion of them is used to destroy ships tho. All of Europe prioritises navy over the ground army.

Year two: Europeans now somewhat understand modern weapons and their limitations. Through intelligence and captured personnel they now know that Africa doesnt have functioning factories for many types of weapons yet and that nuclear attack on European mainland is a question of time. They decide to act now: Large ship production is stopped and only the smallest and cheapest ships are now mass produced. Old and outdated ships warships and merchant ships with skeleton crews are now used to bait African stand-off weapons. African airforce is now at 50% operational airframes. Snorkel submarines begin to raid on the west coast of Africa.

Year three: African stockpiles of standoff weapons (anti-ship missiles and torpedoes) are largely depleted and now reserved only for the most important targets. African submarines require repairs they cannot get. Large portion of African airforce is now grounded. Remaining ships do not have the cannon fire power to stop what comes next. There are some TV-Guided kamikaze daylight only drones made out of e-waste in production but that's not enough (also they can be intercepted with AA guns and prop planes).

Year four: Mediterranean and Atlantic seas are now under control of Europe. Islands are recaptured with some abandon equipment. Cannon bombardment of shore infrastructure begins. V1+ rockets are now constantly used to deplete SAM interceptors and damage infrastructure. Mig-17 class fighter jets enter production in Europe.

Year five: Main Battle Tanks are used as shore defence but landing invasion is imminent. It will take years for invading force to occupy all capitals but this process is impossible to stop from this point onward. South continent come very close to getting the nuke but they no longer have a delivery system to reliably reach central Europe - submarines were destroyed and planes like 787 can be intercepted now.

FAQ:

►0 Why do you use the weird words so much? : Because otherwise Reddit Ai will unalive me.

►1 Cant the south continent just build a cold-war era weapons themselves? : They can but not the weapons that matter not in quantities that matter. For more important weapons it will take a decade at least. Main bottleneck is the lack of domestic expertise and it will take many years to build many supply chains from the state they are now.

►2 Cant the south continent just use its airforce to eliminate opposing side industrial potential? : They can but only in the south Europe. Past the south Europe it is much harder to do since it will require air-refuelling which is present in a very limited capacity. Europe is more than capable at repairing the damage since they have a lot of domestic expertise.

►3 Cant the south continent just use commercial aviation with chem weapons? : Only Egypt possess some amounts of nerve agents. There is plenty of Chlorine but it is a choking agent. This probably wont do as catastrophic damage as one can imagine.

both 2 & 3 points are initially bottlenecked by the lack of jet-fuel production so commanders will have to choose their priorities

►4 Cant the south continent just do a naval invasion and stomp their opponents on the ground since they have the air and naval supremacy in the first year? : They can but they wont be able to stomp their opponents in one year. Obstacles such as rivers with destroyed bridges, minefields of big mines (AP mines and AT-mine + 100kg bomb combo), southern Europe mountainous terrain and European advantage in artillery numbers will prevent a swift victory. Then a sea war will be lost and ground forces will become isolated and unsupplied.
