Reproducible with: 2023.1.0a24, 6000.0.42f1, 6000.1.0b10, 6000.2.0a6

Reproducible on: Windows 10 (22H2), Windows 11 (23H2) (user’s)
Not reproducible on: No other environments tested

Notes:
* Reproduction is inconsistent, but the rate is pretty high

* The Profiler window must be open for the freeze to reproduce

* If you’re not able to reproduce the freeze after ~30 seconds, close the Editor and repeat from step 1 - the freeze should reproduce in a few repeats
