My late 2013 Mac Pro has been crashing daily due to windowserver (151), after I installed macOS BigSur 11.4 (screen freezes including clock, etc.). See crash report below.

Hey there, Dlh345.
It appears that after installing macOS Big Sur, you are experiencing issues with your Mac Pro, like it becoming unresponsive. Besides installing macOS Big Sur 11.4, has there been any other change to your Mac Pro? Do you notice your Mac Pro become unresponsive when doing certain tasks or using certain apps on it? Additional details can be helpful when isolating issues.
You'll also want to make sure all installed apps are fully updated on your Mac Pro: Use the App Store to update apps on Mac - Apple Support
You can also see if this issue happens in a new temporary user: Set up users, guests, and groups on Mac This step can show if the issue is happening system wide on your Mac or only if its happening with your specific user.
Take care!
