How do I restore the GCP App Engine default service account?

I accidentally removed the App Engine default service account (account in the appspot.gserviceaccount.com domain) from the IAM and Administration > Service Accounts and IAM and Administration > IAM in GCP.

I would like to restore my service account because I can no longer use any services related to GAE, but I have not been able to restore it properly.
Could you give me some advice on how to restore it?

The following are some of the restoration methods you have tried and the results:

I will answer because it was exactly the same.

As shown in the issue below, you said that it was being handled as a known issue as of 1/8th, but there seems to be no progress as of 1/30th, so I think we have no choice but to recreate the project.

This is known issue, and engineering is already working towers a fix. No estimated time to resolution has been set. Meanwhile, you may follow developments in this thread.

see: https://issuetracker.google.com/issues/122163562

F.Y.I. By the way, when I asked a question on the gcpug rack, kind people told me in seconds.
