Thank you so much for the report! Thankfully the log showed the issue for me!
Somehow your CPU is being reported as having a single core and the AI (as in, non-genAI) thread that simulates the moves is startng with 0 cores (as I avoid taking over the main core).
Processor: AMD Ryzen 5 3600 6-Core Processor, 1 core(s) @ 3818 MHz
(notice that even though it says 6-Core Processor, Unity is only seeing one)

I will prepare a fix ASAP!!
