I saw this issue documented a few years ago as a Unity issue, and that is was supposedly fixed in all supported versions.
I wanted to verify if:
1.) This is a Unity Error (I can’t imagine it’s on my part, I’m not trying to save/load 11TB ever.)
If it is somehow my fault, maybe where I can look to in order to better diagnose this kind of issue?
2.) If this is a fluke and I should expect to never see this again, or if this will happen more and more.
Call stack indicates an internal bug, apparently when drawing the Console panel. Maybe some crazy text gets logged and rendering it causes a problem. Always helps to list which Unity version you’re using.
More so: when you are using a BETA version as in this case you are supposed to keep updating to every newer beta version every fortnight because you are TESTING the editor and REPORTING any bugs, but not using these beta versions for production use.
