I already contacted NI support, who said they would create a CAR, but after 2 years this bug still exists in LV2022, so I thought it would be great to document it here.
Description: in LV2019, LV2020, LV2022... Let's say you have a class with a static dispatch property, and access this property from a method using a property node.
It can happen that removing the property from the project explorer and then opening the method (that uses the property node) will crash LV.
To narrow down the bug: It only happens with static dispatch, dynamic dispatch is ok. Also, if the VI using the property node is not inside a class, it seems to work fine too.
You can reproduce this crash with the attached example project (min version: LV2019)
