i am working on macOS 10.14.6 and i cannot remember that i had any "unspecified" hangs/freezes in LC the last weeks or months.
I had 2 or 3 hangs when i tested some code that used tsNET, but those hangs were caused more by my code and not by LC. ;)

But no hangs when i was just coding or creating/building stacks.

The last 2 days i've worked with LC 9.6.2 rc5.
Each day i had LC running/opened for about 12 hours, although i was working in total about 8 hours each day with LC.
Most of the time i was in the editor. But I ran a ton of shell commands using shell() function while testing my stack.
I did not had any hang/freeze. 

On what OS are you and did you do anything special in LC when the hangs appeared?

Currently i really cannot confirm such hangs,  but of course I don't want to rule out the possibility that they exist.

So if you have a recipe i would be really happy to test here.

Btw: The only thing i experienced 3 times with RC5 yesterday was, that for whatever reason all objects, which i had setup in geometry manager to scale or move when the stack is resized, were automatically resized to very large value (width and height) without resizing the stack.
Suddenly they were resized. Even resizing them manuall, did not get geometry manager scaling/moving the obejcts again. I had to restart the LC, reload the stack and de- and reactivate the geometry manager settings for each object. After that it worked until the next "resize".
I really have no clue what was causing this. Today i did not have this problem.

All the best.
