Can you run this from an elevated command prompt and see if this fix it

takeown /f “C:\Program Files\WindowsApps\Microsoft.WindowsAppRuntime.1.1_1003.565.600.0_x64__8wekyb3d8bbwe” /r /d y
icacls.exe “C:\Program Files\WindowsApps\Microsoft.WindowsAppRuntime.1.1_1003.565.600.0_x64__8wekyb3d8bbwe” /grant Users:(RD,R,REA,RX) /t

I seem to be having this same issue, but on Windows 10 21H2, using VS Version 17.5.0 Preview 1.0 as well as 17.4.2. I tried the takeown and icacls commands on the C:\Program Files\WindowsApps\Microsoft.WindowsAppRuntime.1.2_2000.684.1510.0_x64__8wekyb3d8bbwe folder, but it didn't fix it. Are there any other workarounds?

Same issue for me - unable to run the workaround scripts in my office environment. Rollback is not showing as an option for me on the VS installer either.

Windows 21H1 19043.2251, Visual Studio 17.4.2

Same. Windows: 21H2. Visual studio 2022 17.4.3

Same issue here. Hot reload worked for a day and then just died. I can't run any workaround scripts with my company laptop. Now I'm forced to continue development on my own PC.

The workaround worked for me after I executed against all folders matching "*windowsappruntime*" in 'C:\Program Files\WindowsApps'.

From an elevated powershell prompt:

cd 'C:\Program Files\WindowsApps\'
ls *windowsappruntime* | % {
    takeown /f "$_" /r /d y
    icacls.exe "$_" /grant ('Users:(RD,R,REA,RX)') /t
}

Note: if the language of your OS is not english, you have to change the value of y accordingly.
