Windows audio and video playback help

launcher 64 worked on my WIN 10 computer last year but a friends laptop with WIN 11 it just disappears when you open it. Now thats happening on my Win 10 computer.
I tried the Autoupdate.exe and its doing the same.
I cant find any fixes
help please

That is quite odd to have occur.
Please try executing the main application, \Tools\Settings64_portable.exe

If that does work, press the [RESET ALL] button to eliminate any rogue settings your system may have.

I discovered and fixed some existing Application instability which has been fixed in current releases.
Be sure you are using at least wersion 18.4.3
