The fix is so terrible that it comes with a warning only to do it if you're absolutely sure you understand what you're doing, along with the warning that I only know for certain that it works on a Ryzen 5 2600 CPU - it may work for other CPUs but I have no way to test that. It's a fix I saw posted and ignored because, as the admin replied before locking said thread, it's dangerous and there's no reason it would actually work, but eventually independently found myself at: overvolt your CPU. Very carefully, just by a little bit. I don't understand why it works, just that it fixed the regular crashes I had in Clair Obscur, Helldivers, and Palworld, and some of the crashes in Romeo Is A Dead Man (the latter also has other crashes related to the GPU). By all rights it shouldn't work and suggests some very weird behaviour from UE5, but somehow it did. It comes with the side effects of needing really good cooling and potentially shortening the CPU's lifespan, so it's imperative you look for alternative solutions that aren't stupid and dangerous first.
