Found it… getting to work now…

@Prince213 I did some more checking on the ShadowDrive AppImage. The image starts and then in ~/.cache/appimage-runner a cache file for this is created… when the app is stopped or the system rebooted, the cached folder remains there. However, with the cached folder being there, the AppImage does no longer start, neither using the AppImage in the directory, nor one of the executables in the .cache directory. I have to manually remove the cached files and then the AppImage starts again.

I have no idea, if that’s related to this particular appimage in particular or a general issue with NixOS. I don’t run any other appimages, so I can’t try. I know you are not using appimages yourself, but I think a solution would be to empty the ~/.cache/shadowdrive directory on reboot / shutdown / startup. Is there any not too complicated way, to achieve that? Maybe using a cron?

You might be able to use wrapProgram, which has this flag:

          # --argv0        NAME    : set the name of the executed process to NAME
          #                          (if unset or empty, defaults to EXECUTABLE)
          # --inherit-argv0        : the executable inherits argv0 from the wrapper.
          #                          (use instead of --argv0 '$0')
          # --resolve-argv0        : if argv0 doesn't include a / character, resolve it against PATH
          # --set          VAR VAL : add VAR with value VAL to the executable's environment
          # --set-default  VAR VAL : like --set, but only adds VAR if not already set in
          #                          the environment
          # --unset        VAR     : remove VAR from the environment
          # --chdir        DIR     : change working directory (use instead of --run "cd DIR")
          # --run          COMMAND : run command before the executable
          # --add-flags    ARGS    : prepend ARGS to the invocation of the executable
          #                          (that is, *before* any arguments passed on the command line)
          # --append-flags ARGS    : append ARGS to the invocation of the executable
          #                          (that is, *after* any arguments passed on the command line)
          
          # --prefix          ENV SEP VAL   : suffix/prefix ENV with VAL, separated by SEP
          # --suffix
          # --prefix-each     ENV SEP VALS  : like --prefix, but VALS is a list
          # --suffix-each     ENV SEP VALS  : like --suffix, but VALS is a list
          # --prefix-contents ENV SEP FILES : like --suffix-each, but contents of FILES

Cool! Once again, thanks. This worked.
