"Permission denied" running `er-patcher`

[l0b0]

Describe the bug

Running any seemingly valid er-patcher command seems to result in the same issue:

$ er-patcher -- %command%
/etc/profiles/per-user/username/bin/er-patcher:133: DeprecationWarning: pathlib.Path.link_to() is deprecated and is scheduled for removal in Python 3.12. Use pathlib.Path.hardlink_to() instead.
  f.link_to(game_dir_patched / f)
Traceback (most recent call last):
  File "/etc/profiles/per-user/username/bin/er-patcher", line 138, in <module>

PermissionError: [Errno 13] Permission denied: PosixPath('/mnt/foo/SteamLibrary/steamapps/common/ELDEN RING/Game/er-patcher-tmp/eldenring.exe')

Steps To Reproduce

Steps to reproduce the behavior:

1. Verify integrity of game files in Steam
2. cd into the Elden Ring Game directory
3. Run er-patcher -- %command%

Expected behavior

Should run the game.

Additional context

I have unpacked Elden Mod Loader 3.2 into my Game folder, in case that's relevant.

See also https://github.com/techiew/EldenRingModLoader/issues/8.

Making the relevant files executable results in a different error, which looks like it's trying to run eldenring.exe directly without WINE:

$ chmod a+x dinput8.dll eldenring.exe er-patcher-tmp/eldenring.exe 
$ er-patcher -- %command%

Looks like I can't run er-patcher from the command line, but changing the launch options within Steam to er-patcher -c -v -s -- %command% worked. This should probably be documented.
