Unfortunately there was an error. File/directory sizes could not be determined.

Hi, as the other thread was closed, I start a new one. I also get the message

“Unfortunately there was an error. File/directory sizes could not be determined. Reload to try again.”

Here’s the Debug Info

WordPress-Datenbank-Fehler: [Unknown collation: 'utf8mb4_unicode_520_ci']

BTW: At first activation attempt, I was also shown the “The plugin does not have a valid header.” error message on a plain page. But it worked when I clicked on “activate” a second time.
