Same issue.

Initially at a couple hours. Then slowly went down to 20-30 minutes.

Initially just froze or crashed to desktop.

Now it’s hard rebooting the system at crash.

I've stopped playing because of all the crashing. I was frustrated, but persevering when it just crashed to desktop; the last 5 ~ 10 were a straight black screen/reboot at random times. CPU & GPU sitting at 60~65c so no temp spikes. Very disappointed in Ubisoft with this.

I've disabled overlays, set whitelists, etc. Even shifted memory off XMP to base rate. Still happens.

Threadripper 2950x
64GB DDR4 @2133 base; 3200 XMP 2.0 max; typically run @28xx
Samsung 970 Pro NVME O/S drive
Samsung 860 EVO SSD gaming drive
ASUS 3090 TUF OC (No overpower; custom increased fan curve)

I rolled back to NVidia 461.40, and went to partial selective startup; left Dropbox, mouse, MSI Afterburner, & BitDefender on. Was able to play 3x sessions totalling about 3 hours with only 2x crashes vs. the usual 3x per hour. The driver rollback had the biggest impact; selective-startup didn't really seem to have much impact except for the new Epic Network Services optional install; that was crashing stuff.

Maybe it’s my issue too?

I pre-loaded the game, and ran it yesterday for multiple hours just fine. I come back to it today, try to load it up, and Ubisoft Connect just spins. I verified files; it fixed a couple things. Still no luck. I verified again; no issues found. Still no luck. Uninstall and re-install. Still no luck. I try adding -BattlEyeLuancher to command line. No luck. I tried setting to run administrator. Still no luck. Go to offline mode, same issue. Checked the logs, no errors shown. What gives?

I should also note that running the game directly it shows up as running briefly as a process, then exits and calls Ubisoft Connect and it "Prepares to launch the game."

Any assistance it appreciated.
