I can't figure out the cause easily from the backtrace, it crashes in tslot_thread_start while rendering the SSS prepass and doing multithreaded depsgraph update at the same time, so I guess this is because of recent threading changes by @sergey.

I assume this is the same cause as #38006. See there for a patch to fix it.
