I ran a full update on my KDE Neon instance on Saturday 12 February. This has caused Wine and Crossover office to stop working. All the Windows applications I run (mainly Office 365) to stop working. It has also caused Zoom to stop working.

Zoom doesn't throw any errors. It's usual splash window opens and then immediately closes.

Office applications (run via Crossover Office) throw a pretty standard application error full of the usual bumpf.

Unhandled exception: 0xe0000002 in 32-bit code (0x7b00fd82).
Register dump:

Followed by a big long dump which ends with

System information:
Wine build: wine-6.0-9510-g8700de06498
Platform: i386
Version: Windows 7
Host system: Linux
Host version: 5.13.0-28-generic

Is anyone else experiencing any similar issues? Anyone have any clues as to the fix?

Thank you

Well, this morning everything simply decided to work. I can see no reason for this.
