Need help troubleshooting internal server error after upgrading from 18.0.0

I have been getting an internal server error issue that I can’t seem to track the source of. Here’s what info I have:

Nextcloud.log
{"reqId":"REDACTED","level":0,"time":"2020-10-07T05:25:54+00:00","remoteAddr":"REDACTED","user":"REDACTED","app":"workflowengine","method":"

Apache.log:

AH01797: client denied by server configuration: /var/www/cloud/config/getuser

I can’t seem to find anything else that’s useful. Files are syncing just fine, but the web interface won’t load. I’m not using Fail2ban and “Satisfy Any” is already in the server config so those are no solutions.
