Hello guys. I'm also having this same issue. Composer revert didn't work and I'm stuck.

go to bootstrap/cache and delete config.php, packages.php services.php.
Then install an older version of the library.
I installed 7.14.0 and it works

Been having the same issue and this worked.

In case future readers don't know, the way to install specific packages versions is by removing the '^', like this:

composer require "spatie/laravel-medialibrary:7.14.0"
