Sudden LS Error

I had to manually delete the LS plugin today when I saw an error on my site trying to log into the admin panel, got the critical error message.

Then, error log file shows this:

When I reinstalled the plugin, the error came back and couldn’t log into the admin panel. Everything was working just fine, unchanged config for weeks until this morning. Maybe an auto update? How can I fix this? Usually, deleting plugin allows to reinstall and fix that error, not in this case.
