As noted in #1143 the wslg.exe binary probably has been moved (to C:\Program Files\WSL\wslg.exe). If you, like me, started your linux GUI apps via an automatically generated shortcut and then had this message, just check your start menu, in my case those have been generated anew and you might have to swap your old shortcut for a new one.

But since you did not write how you opened your GUI app, I can only guess as well.

Hello, Mr1chter:

Thank you for your reply.
Earlier, I checked the system-generated Linux GUI shortcut and found that wslg.exe was indeed moved from "%USERPROFILE%\AppData\Local\Microsoft\WindowsApps\MicrosoftCorporationII.WindowsSubsystemForLinux_xxxxxxxxxxxxx"
to
"C:\Program Files\WSL".

I will correct all the referenced paths.
