This is still open as of 1.20.1.02 update.
I see the same issue. We use /spreadplayers command blocks, and this broke several systems now that players spawn within the block.
This issue is still open as of 1.19.80.02.
After some digging - it appears that support for directx10 GPU's has been dropped as of this update. I've learned that the feature set of the GPU and the version supported in windows are different. My laptop has a 9600m GT which only supports DX10, so my system is now incompatible.
Dropping support for this and other older devices is mentioned in the 1.14.10 patch notes, but not in this update for some reason.
Updated fine on one PC, but I am unable to update the older laptop. I've tried all different methods of resetting / clearing the Microsoft Store, but the install always fail.
This is still open as of 1.20.12. Can we have an update on this?
