Roblox won’t install on Windows 11 (installer + Microsoft Store both fail)

Hi, I’m trying to install Roblox on Windows 11 but it always fails with the error:

“Continue without installation flags”

The installer runs for about 1 minute, then shows that message and stops. This happens every time.

I also tried installing via Microsoft Store, but that fails as well.

I basically tried everything but sadly nothing works. Has anyone fixed this exact error or knows what causes it?
