I am facing this assertion error in every list which is included a column type of managed metadata.

Even if I create a new custom list and add one metadata type column, this error is popping up when I click on quick edit.

Can anyone give a clue where I can start to fix this error?

Finally the issue is resolved.

This issue occurred because of the debugging mode was enabled in SharePoint web.config file for that web application.

I disabled the debug mode and reset the iis AND error is gone. :)

    Hi @Fahim Afser ,

    Per my test, I am not able to reproduce your issue. Are you using any code in your list or the page? If you try in the OOTB list, will the same issue occur?

    In addition, please test using other browsers, like Chrome or Firefox, check if this issue occurres.
