Description

I tried to launch 100 environments I got a UnityTimeoutException when creating the 66th one. I checked multiple times and the exception always occurs on the 66th instantiation.

I am using gcloud with a K80 GPU and the memory usage is less than the available memory.

Contributor guide

Research direction
Check the error handling in the environment launch code to identify why the 66th environment fails. Review memory and GPU constraints, and examine the timeout settings. Look at the existing comments for potential clues about race conditions or resource limits. Test with a minimal reproduction script to isolate the issue.
