Description

• Expected behavior: gz gui launches fine
• Actual behavior: gz gui crashes

Steps to reproduce

1. launch gz sim in server mode, e.g. gz sim -v 4 shapes.sdf -s
2. launch gz gui: gz sim -v 4 -g -> crash

Output

Other notes:

• rendering sensors work fine
• I've actually managed to launch the gui probably around 1 in ~5 times. There could be some race condition happening
• Qt version:

  $ brew info qt@5
  ==> qt@5: stable 5.15.7 (bottled) [keg-only]

[iche033]

turns out the gui crash is a red herring. The crash was caused by the component inspector trying to display corrupt or null data received from the server. Closing this issue as it's not related to gui.
