There are no real steps to reproduce this issue, as it is based on timing.

Unity can crash during a domain reload if a merge operation is currently ongoing. This is because we release all native resources, such as the LMDB database, when the OnDisable is called, which happens before threads are stopped.

*Steps to reproduce:*
# Open Unity
# Start an indexing operation.
# Wait until the background progress says "Merging artifacts...".
# Trigger a domain reload.

*Actual results:* 

Unity crashes.

*Expected results:* 

No crashes.

*Reproducible with versions:* 6000.3.0b1, 6000.4.0a1

*Not reproducible with versions:* 

*Can’t test with versions:* 

*Tested on (OS):* Windows 11
