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

I've been having the same issue with my surface with crashes related to heatcore.dll and DWM.exe

The issues with Zoom are well documented and across many devices so I won't focus on that here, especially since I experienced this issue even without Zoom being installed. I did get a replacement surface due to my issues and I am still experiencing the same crashes with the same cause. It does appear to be related to sleeping (guessing that heatcore is related to power management based on its name). Hopefully since this appears to be an emergent issue and not tied to a particular device its a software issue and can be fixed in the future. 

I just wish that there was a way to get Microsoft to acknowledge these issues in a bug tracker or something similar instead of just yelling into the feedback void.

I called MS and they told me the pen crashing issue was related to OneNote, but I did not have it open when it crashed on me today. They also said Zoom is causing issues not just in Surface line, so they discouraged me from getting a replacement.

I am now trying the rename HeatCore.DLL tip I mentioned above. Hopefully, I no longer see any more DWM crashes involving HeatCore.DLL

EDIT: It appears sfc /scannow brings the file back. Regardless, when I tried deleting the renamed HeatCore.DLL, it wouldn't let me, since DWM was using it. So it doesn't appear this actually will work in any case. Not even through rebooting into WinPE and deleting through Command prompt. This is one file that won't go away apparently.

I saw in another thread another user might have had luck renaming/deleting HeatCore.DLL, which is in both our error dumps. If you are having issues still, might be worth a shot? 

Apparently I jinxed myself since upon using my pen as I was writing this thread I was able to get DWM to crash. I think at this point since I've gotten blurry text in Zoom and now DWM crash while using pen today, I'm going to ask MS to send me a replacement device.

I think you're right. I could definitely it see being the result of a new update. I don't have access to old Reliability Monitor since I have updated to 20H2 and clean installed, and I don't remember having such a frequent issue earlier in the year.

I'll be keeping an eye on it throughout this week. I feel like it has to be a recent Windows or driver update. I would frequently have my Surface go between on and sleep mode while at work or during my classes and use the pen without these kind of issues in the past.
