As the title says. It took me 3 days with a back and forth with the Ubisoft support to fix this. Before wednesday, everything was working fine. I'm always coming home to play 1 or 2 hours of r6. I didn't change a single thing on my PC, and the performance of its components is absolutely normal. But suddenly on thursday the game started crashing reliably in the 2nd round of each match. At first I thought it's somehow related to the 2nd round, but I figured out after a few tries that it's more time related. It will crash after 5 - 6 minutes into a match.

Tried like 20 different fixes suggested by the Ubisoft Support. Nothing they suggested worked. Deinstalling and reinstalling everything, searching for newest updates for windows/nvidia, deactivating full screen optimization, running the game as admin, deleting %temp% folder contents, playing other games to test if they would crash too, etc.

Finally, I randomly stumbled upon a Ryzen specific bug that was also already existing 4 years ago. I had to deactivate SMT (Simultaneous MultiThreading) from my BIOS settings in order to stop the always reproducable crashing.

This is simply not acceptable. Please fix this immediately, I don't want to be forced to always deactivate SMT when I want to play R6. This is insane, my 12 Core processor won't have its 24 threads due to this. Ubisoft, you're crazy. At least give us an option in-game to deactivate it... or give me back my money. It took me 6 hours of non-stop debugging.
