Sudden error in Prestashop


if the debug mode is not enabled, BO is showing following error message:

Attempted to load class "AdminLegacyLayoutControllerCore" from the global namespace. Did you forget a "use" statement?

[Symfony\Component\Debug\Exception\ClassNotFoundException 0]

If I enable debug, BO is accessible again, but new orders are showing no status (screenshot attached).

Here are the steps that led to that error:

1. Yesterday no issues at all, today all combinations for all products were missing. And I haven't touched a single file, setting, etc ...

2. I cleared cache and tried to change PHP version to see if the issue persist

3. After changing PHP version I started to receive the "Attempted to load class...." error. I switched back to previous PHP version but the error message persists.

Thank you.
