About 1 month later I did crypto mining on my VM and then got a alert and then i just deleted that VM and then I created a new VM to do Codes and after a month GCP deleted my VM and said that i violated their Terms of service and then said me to request a appeal to restore my project and i appealed them and after half an hour they said me that:
Dear Developer, Thank you for your appeal.

But after waiting for nearly 5 hours my VM is not yet Restored and in the Activity column its saying that: enter image description here
They said me that they Reinstated my Project it means they must restore my VM.
If a project has been shut down, resources under that project gets deleted too.
Thus, deleted VM instances/snapshots/disks are not recoverable after project deletion.
