Unable to create new project after updating to version 13 (error 500)
Updated to version 13 (using docker ce version) and everything looked fine until I tried to create a new project, then was greeted with this screen:

I attacj my `production.log` file, where there is the error:
```
Completed 500 Internal Server Error in 53ms (ActiveRecord: 13.9ms | Elasticsearch: 0.0ms | Allocations: 17921)
NoMethodError (undefined method `first' for nil:NilClass):
```
I already tried cleaning the cache as recommended in [this issue](https://gitlab.com/gitlab-org/gitlab-foss/-/issues/58703), with no luck.
I also tried wiping up the docker and reinstalling from a backup. But it stays the same.
Any help is appreciated.
