It's crashing inside the app itself.
Comment 2 Christoph Feck 2020-04-28 06:34:48 UTC 
The crash is in the Mesa software OpenGL renderer. If your hardware supports OpenGL, this is very likely a setup problem.

If you really need to use OpenGL software emulation, and the bug is reproducible with newest Mesa version, please report this issue directly to Mesa developers via https://www.mesa3d.org/bugs.html
