PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:\\Users\\jaraco\\.local\\bin\\xonsh.exe'
Afterword, the shell is unusable and the state (injected modules) is lost.
PS C:\Users\jaraco> xonsh
Fatal error in launcher: Unable to create process using '"C:\Users\jaraco\.local\pipx\venvs\xonsh\Scripts\python.exe" "c:\users\jaraco\.local\bin\xonsh.exe" ': The system cannot find the file specified.
PS C:\Users\jaraco> pipx reinstall xonsh
Nothing to reinstall for xonsh 😴
Expected behavior
Ideally, the workaround used for python.exe would also be used by xonsh.exe (move the file to a temporary directory when unable to delete). If that can't be done, it would at least be nice if it could fail early and not leave the reinstall half-completed.
