Expected result: Unity does not crash
Actual result: Unity crashes

Reproducible with: 2021.2.1f1, 2021.2.8f1, 2022.1.0b4, 2022.2.0a2
Not reproducible with: 2019.4.34f1, 2020.3.26f1
Could not test with: 2021.2.0f1 ("Assertion failed on expression: 'exposedParameterCacheSize == constantExposedParameterCount'" error while trying to load the Prefab with Audio Mixers)

Notes:
