Latest Intel Arc driver seems to be crashing Vegas 20

I'm using the latest version of Vegas 20. I have an AMD 6900XT as my main graphics card but I'm also using an Intel Arc A770 16GB as my hardware decoder. I got a notification that a new driver was available so I installed it and I can no longer play back a timeline or render without crashing. The Intel driver version is 31.0.101.4644

This happens mainly in 32-bit floating point (video levels) mode (not 8 bit) but I always render in 32 bit and it worked fine before this driver update. Is anyone else noticing this issue? If I turn my hardware decoding off I can render but it takes much longer.

Just updated my 11900k/6900xt/A770 system from Intel 4502 to 4644 and so far so good with vp20 b411. I'm configured to use the 6900xt in video prefs and the Arc for decoding in i/o. Just did a vce test render of an 8k hvec 422 clip in a 32-bit video range project and it went through fine. Qsv render good too.

Btw, I noticed the update screen said there might be a firmware update and that monitor should be plugged into the Arc to get it. So I did that and there was indeed a firmware update to the a770. Moved hdmi back to the 6900xt afterwards during the reboot before my test renders.

Just shot an 8k hevc 420 clip for editing, grading, and rendering with vp21 and will see how that goes.

Thanks for checking that. I am able to render and play one clip at a time (in it's own project) but a project that has multiple clips is a crashfest. The footage I am using is Sony XAVC HS 10bit 4K files but the crashes happens with XAVC S 8bit 720P proxies as well. So I guess all types of XAVC. I'm guessing there's no way to go back to a previous firmware with the A770 so I may just have to upgrade to Vegas 21 to see if that fixes it. Let me know how 21 works for you.

And crap...I do remember the firmware update but I didn't plug my monitor in to the Arc. Hopefully I didn't mess something up. I'm going to try and reinstall and see if anything changes.

Ok it was the firmware update. Since my monitor wasn't plugged in to the Arc, it didn't do a firmware update but now that I reinstalled the update with the monitor plugged in, everything works again. Thanks
