[Linux - AUR] Crashes on launch after showing a blank error

[KBD20]

This was using ChaoticAUR repository but I tested my own AUR build the issue is the same.

Graphically it shows a blank error window titled 'steam', the Terminal outputs a TypeError for join() on crashing:

Traceback (most recent call last):
  File "/opt/sme/main.py", line 46, in <module>
    main()
    ~~~~^^
  File "/opt/sme/main.py", line 35, in main
    main_window = MainWindow()
  File "/opt/sme/gui/main_window.py", line 78, in __init__
    self.create_main_window()
    ~~~~~~~~~~~~~~~~~~~~~~~^^
  File "/opt/sme/gui/main_window.py", line 333, in create_main_window
    self.mark_installed_games()
    ~~~~~~~~~~~~~~~~~~~~~~~~~^^
  File "/opt/sme/gui/main_window.py", line 358, in mark_installed_games
    install_path = os.path.join(
        library, "steamapps", "common", install_dir
    )
  File "<frozen posixpath>", line 90, in join
  File "<frozen genericpath>", line 188, in _check_arg_types
TypeError: join() argument must be str, bytes, or os.PathLike object, not 'int'

Here's the appinfo.vdf if it's needed.

I also tried it as root as a test and it did run but asked where steam was installed, then crashed once I pointed it there with the same error.

Removing install_dir or renaming it, in my case to "installdir", from line 358 in main_window.py allows it to work with no apparent issues.
