@larry-oak this line appears to be the cause of the backend container crashing:

penpot-backend_1 | [0.028s][warning][os,thread] Failed to start thread “GC Thread#0” - pthread_create failed (EPERM) for attributes: stacksize: 1024k, guardsize: 4k, detached.

Here are some people with a similar error, that claims to be solved by updating docker to 20.10. Could you try updating it?

In other words, it is not a penpot issue, the docker container is unable to create JVM or nodejs threads, so you are not able to use JVM or nodejs. The stack trace in the logs indicating a pretty deep problem of compatibility between your operating system and the docker.
