Cannot launch the game through the RimPy app

[TheRedBaron56]

Application starts up just fine, mods can be arranged and enabled/disabled at will. Pressing "Run!" produces absolutely no result. Pressing "Autodetect Paths" results in a crash. Running the app through the terminal results in the following:

Gtk-Message: 17:46:55.377: Failed to load module "xapp-gtk3-module" Sandboxing disabled by user. 3.0145991939999703 js: Uncaught ReferenceError: qt is not defined js: Failed to report error: ReportError() was called without an error to report. js: Uncaught TypeError: Cannot read property 'lastChild' of undefined js: Failed to report error: ReportError() was called without an error to report. js: Uncaught TypeError: Cannot read property 'parentElement' of null js: Uncaught (in promise) TypeError: Cannot read property 'filter' of null
Please advise.

Same here, hitting the run button does nothing.

I've not encountered this issue, but maybe try setting the paths manually.
