We're sorry, an internal error occurred

Hi guys,

I'm facing the common error "We're sorry, an internal error occurred."
Checked log and error message is: "A theme with 'DefaultClean' system name is already defined"

The problem appears right after
1.  I tried to clone Default Theme to MyTheme folder
2. Upload MyTheme in Local Plugin => application restart automatically
3. It's unable to access my website anymore.

Any solution to fix this issue??

Note: I use docker to deloy my website

did you give the new MyTheme a unique SystemName in its theme.json file?

Unfortunately, I forgot that file, already remove the file, but it's still unable to login.

The new theme requires a theme.json file, please recheck every step here:

Thanks, I fixed the issue base on your link:
1. Re-create theme following your link (at this time I change the name in theme.json)
2. Re-upload and restart docker => website back to normal :)

Cheers
