Repeated Daily Crashes of Desktop Window Manager in Reliability Monitor When Using Pen

I'm not sure if this is 100% effective, but it appears having my surface connected to power when I touch my screen for the first time with my pen prevents the DWM/heatcore.dll crash. Hoping it works for others! I'll update in a week.

Funny, I was doing something and got a blue screen shortly after posting that and my Surface did the first two updates during the restart. Used the pen and had the issue again.

I know these updates occurred a few days back as well:

Will report back later today after doing the optional KB5001567 I mentioned above. 

Edit: Problem still persists after the optional KB5001567 I mentioned.

Hello, Thanks for mentioning the updates! Yes, there were a few updates a few days ago concerning Surface and Intel Corp extension. I am also downloading the optional update.

I had the screen freeze on me 4 times yesterday and once this morning.

Would Microsoft be aware of this issue?

Cheers

That's the Feedback Hub submission I did. The share links still shows as https://aka.ms/AAbc54n

I got it again a moment ago. I have KB4589212 pending for update today. 2021-01 Update for Windows 10 Version 20H2 for x64-based Systems and KB4601554 2021-02 Cumulative Update Preview for .NET Framework 3.5 and 4.8 for Windows 10, version 20H2 for x64. Along with an optional KB5001567 2021-03 Cumulative Update for Windows 10 Version 20H2 for x64-based Systems. I'll do those updates in a bit and see if it has any effect.

Exact same issue, using the Pen causes a freeze & then a black screen. Applications like Teams have the windows blacked out after the freeze and have to be quit and restarted.
