Lost admin access to wordpress

I had a simple installation of WordPress running well.
Self-hosted, on docker, I have terminal access.

After I inserted ALLOW_MULTISITE to the config file, it was changed to multisite.
After inserting the multisite configuration script to the .htaccess, I lost it.

All plugins were deactivated before it.

1 – I tried to get back to the first install, no result.
2 – Deleted wordfence file, no result
3 – LOGS on wordpress container:

[Tue Sep 27 19:01:03.129594 2022] [core:error] [pid 22] [client 172.70.178.202:0] AH00124: Request exceeded the limit of 10 internal redirects due to probable configuration error. Use ‘LimitInternalRecursion’ to increase the limit if necessary. Use ‘LogLevel debug’ to get a backtrace., referer:

Since I can’t access the WordPress at all, and even the website is showing:

Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.

Is not helpfull since I can’t access my dashboard at all.

I also tried to re-install wordpress using different passwords, no result. I then re-installed the container using the same password, since it is connected to database and npm, and the .htaccess is clean, only with the code I found here on the community, no result.

I can’t simply call the hoste, I am self-hosting.

Next step is to bring down all the installation the instance and do it all from scratch, but I am sure I will get the same trouble the moment I try again to turn it into multisite.

Can anyone point me to the problem please?
