Seems to be a graphics openGL crash.
GPU drivers need to support Qt5 (the framework MM is built on)
You might try this:
Shut down MM.
Rename meshmixer.ini to meshmixer2.ini (just to have a backup)
You'll find meshmixer.ini at:
Windows: C:\Users\User Name\AppData\Roaming\Autodesk\meshmixer.ini
(NOTE: AppData is hidden by default, so you might have to enter that path manually or choose to show hidden files.)
Mac: ~/.config/Autodesk/meshmixer.ini
(Note: .config is hidden by macOS defaults, so you might need to set macOS to show hidden files)
>>> MM will write a default ini on its next launch.
Maybe this fixes your issue.
If NOT:
Run MM. Before trying to load or doing something in MM:
Go to MM's Preferences (via menu) and disable ShowViewCube on its General tab.
Maybe this fixes your issue.
If NOT:
Run MM. After loading any object :
Optional: Go to menu/View and enable ShowPrinterBed (if the bed isn't visible).
Look at the dropdown box at the upper right in MM's window.
If there's something like "NoPrinterSelected" open the dropdown and activate some printer (just to set one).
You now may hide it via View menu now.

That're things which fixed similar issues.
There seems to be something wrong with support of NVIDIA Quadro GPUs. What graphic card are you using?
