Dialogs not opening

[s8foschm]

I have had an issue for the last few days, where vscodium on my system does not open any dialogs. When I want to open a file, trying 3 different options (file menu -> open file, Ctrl + O, and entering "open file" in the command palette), nothing happens. Same goes for the "Save as" menu.
What could cause this? Also, is there a way I could find error logs or something like that, so that I can provide more information?
I am running the latest version of VSCode from the AUR, on a Manjaro system with i3 Window Manager. Everything is up to date.
