Game crashing on startup - assert errors

Hello

Running Windows 11 with latest version of Sins 2. Cannot start either primary game or test game and keep getting assert errors. No windows updates have occurred recently on my system. An example of one of the errors (i get 4 similar notifications before game closes): 

ASSERT(a.id != b.id)

version=1.21.9 (121)

log=C:\Users\ehunt\AppData\Local\sins2\logs\sins2_log_21672.txt

Uninstalled and reinstalled game. same set of errors.

Please advise
