[2023] Game crashes at start - Error - Simulation failed: EndDeserialize(PropManager)

Simulation failed: EndDeserialize(PropManager) is usually caused by a combination of Prop Anarchy and Extended Managers Library. Make sure you have the updated versions of those mods, and if that doesn't help, I recommend unsubscribing both and getting Prop Control instead.

I spotted algernon released a new mod which may help to remove Extended Managers Library and Prop Anarchy. Note that the mod is still in testing so make sure to read the description carefully.
