Because the bug appears to be caused by a compatibility issue between Windows 11 and the.NET Framework, reinstalling versions 3.5 and 4.8 should fix the issue. Here’s how you do it:-

• Next to the Start menu, click the search symbol and type ‘switch windows features on or off.’

• When you select the appropriate option, a window similar to the one below will open.
• Uncheck the boxes next to.NET Framework 3.5 (includes.NET 2.0 and 3.0) and.NET Framework 4.8 Advanced Services, then check them again.
• To implement the changes, click ‘OK’ to confirm, then restart your device.

If it doesn’t work and the app crashes are becoming too much of a nuisance, you can delete the update entirely. This procedure, however, will only function if it was installed today or yesterday-

• Open the Options menu.
• From the left pane, select ‘Windows Update,’ then ‘Update history.’

• Scroll down to the ‘Related settings’ area and select ‘Uninstall updates.’
• Here you may see any latest updates that have been installed. Click ‘Uninstall’ next to the KB5013943 update, then ‘Uninstall’ again to confirm.

• After you’ve finished, restart your device to effect the modifications.

If it doesn’t work, the issue could be related to the prior optional update that caused the app crashes, to begin with. If this happens, or if it’s been more than a day since you installed the update, you’ll have to wait for Microsoft to issue a fix.
