Problems building and launching RS3 on NixOS?

[JasperSurmont]

Using Flatpak on NixOs I manage to get the Bolt launcher running. RuneLite works well, but the rs3 doesn't:

• it either crashes during 'loading application resources'
• or it starts up but only has a black screen.

I would like to debug this, but cannot find any crash logs whatsoever. Is this not a thing? Or are they somewhere stored through Bolt? Thanks!
