Admin Section Throws 502 Error

If I sign in and visit the admin section, it throws the error 502 after few seconds.

Below is the recent error log :

what could be wrong and how can i fix this?

Have you tried disabling customisations?

All of the console errors for the rest of your site disappear when you browse in safe mode:

how can i do this? by switching to another theme or removing component from current theme?

Create a new theme with no customisations, swap to that.

If the issue persists disable all extra plugins in your app.yml.
