I started working on Ubuntu 20.04.3 LTS and I can not open any game object or collection with visual components (GUI, atlases, tilemaps, etc) or those visual components separately. Only scripts, .project, .input_binding files are opening correctly.
I submitted issues:
When opening GUI component in Editor I have a different error message:
Defold version: 1.2.188 alpha
Editor SHA1: 6bfeea3b13d7b8920483ea2cba9c181a8650b84d
Engine SHA1: 6bfeea3b13d7b8920483ea2cba9c181a8650b84d
It’s not something of priority, as I can easily switch back to Windows, however it looks strange and definitely worth reporting
