This bug, however, is invalid (Background apps should continue to run, as they do under Windows).
Maybe it's another bug, but installation of FL Studio freezes when FL Studio try update Microsoft Edge. I suppose installation waits when "C:\users\steamuser\AppData\Local\Temp\MicrosoftEdgeWebView2RuntimeInstallerX64.exe /silent /install" ends working.

Because killing process 145612, helps end installation.
