Bug Unity 5, i9 12900k compatibility

Hey, i'm having issues with Unity 5.3.5f1 since I've upgraded my cpu to a i9 12900k. The 64bit version doesn't start, it stops right after the first blue window on openning. The 32 bit version works just fine BUT I would need the 64 bit version to work, the RAM limitation on the 32 bit is a big issue on my end for some projects.

For anyone wondering why I use this version of Unity and not a more recent one, I use this version for game modding and I can't use any newer one.

If anyone knows about the issue and how to solve it somehow (without having to buy an older CPU ofc) that'd be awesome !
