I didn’t, WordPress did auto updates before that happened, I tried installing older version of WordPress, but the problem is still there.
I checked for a solution online and found this https://youtu.be/ZZmt4KmtIyo
It seems it happened to few more people recently, unfortunately the server won’t allow me to change the file permission to 444 to test this solution.

This is the error log I get every time I log in to Admin, I have to upload wp-load file to restore the website
