Can’t update Appearance >> Widgets “

Hey, I’m using WordPress 5.8.1 and when i try to update widgets in Appearance >> Widgets,
I get an error that says – “there was an error. the response is not a valid json response”. I searched googled and found that people also struggle with the same error regarding text editing, but I couldn’t find the solution with widgets.

I tried everything in this link – https://www.wpbeginner.com/wp-tutorials/how-to-fix-the-invalid-json-error-in-wordpress-beginners-guide/ , but it still didn’t help. Also I updated php version to 8 (was on 7.4) and the WordPress had a critical error.

So I was wondering if someone had the same problem and found the solution?
