[v1.35.5] (standalone) HPG shifter not recognized

<!-- Note: Please search to see if an issue already exists for the bug you encountered. --> ### Affected version: V1.35.5 ### Are your devices running the latest firmware?: Yes; v1.2.1.8 ### Current Behavior: The Boxflat launcher works fine, don't see any errors, but connecting just the HGP shifter using USB does not show up. ### Expected Behavior: Shifter shows up as standalone device. ### Steps To Reproduce: 1. Install latest Boxflat release 1.35.5 using install.sh 2. Launch Boxflat either through boxflat.sh or boxflat command 3. Device doesn't get recognized even when replugging ### Additional info I primarily use the AUR package, but installed the latest 1.35.5 release as I hoped fixing https://github.com/Lawstorant/boxflat/issues/135 would resolve my issue as well. The device itself is recognized by Linux and correctly recognized in a Windows VM to test/update firmware. When using the AUR package: 1. Running `flatbox` works fine, device does not show up though. 2. Running `flatbox --flatpak` results in the following error: ``` (process:30531): Gtk-WARNING **: 19:20:52.283: Theme parser error: <broken file>:1:1: Error opening file /app/share/boxflat/data/style.css: No such file or directory Traceback (most recent call last): File "/usr/share/boxflat/entrypoint.py", line 33, in <module> app.MyApp(data_path, ~~~~~~~~~^^^^^^^^^^^ config_path, ^^^^^^^^^^^^ ...<3 lines>... application_id="io.github.lawstorant.boxflat" ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ ).run() ^ File "/usr/share/boxflat/boxflat/app.py", line 154, in __init__ self._cm = MozaConnectionManager(os.path.join(data_path, "serial.yml"), dry_run) ~~~~~~~~~~~~~~~~~~~~~^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/usr/share/boxflat/boxflat/connection_manager.py", line 68, in __init__ with open(serial_data_path) as stream: ~~~~^^^^^^^^^^^^^^^^^^ FileNotFoundError: [Errno 2] No such file or directory: '/app/share/boxflat/data/serial.yml' ``` 3. It did still work correctly before the weekend, before updating any packages.
