Errors in phpMyAdmin after 'docker-compose build mysql' in Laradock - how to revert old mysql version back?

Question

Docker

I have Laradock

I made changes to createdb.sql to add another database, but after rebooting (down - up) - the database was not added

Then I decided to do 'docker-compose build mysql'

And after the rebuild, phpMyAdmin began to crawl out on my home page mistake:

Notice in ./libraries/classes/Charsets.php#154
Undefined index: utf8mb3

I googled it, it's somehow related to versions and is generally solvable ( https://stackoverflow.com/questions/67421885/phpmy... ) - but I have some Laradock - I can't just get into the code and fix everything or something like that.

In addition, this error has now begun to come out in other projects. And I understand that I do not understand something.

Does he do this 'docker-compose build mysql' in one place or what? (I put a separate Laradock on each project and even make DATA_PATH_HOST different for it)

In general, I don’t know how to fix it back now.

If someone shares their experience - I will be glad.

In general, I deleted all docker images in the system and reinstalled the necessary one through
docker-compose up -d nginx mysql phpmyadmin
everything seems to be working fine now. here is the output it delivered:
