Corrupt RIS file results in import that never completes

[TjerkNan]

Describe the bug
I generated a file that is in the wrong format and uploaded it.
There is now one import that is not completing (See screenshot).
This is not blocking as I can still import correct RIS files and those imports seem to succeed.

Please note that it's not possible to clear out the failing imports as of this time.

I've collected some papers from Google Scholar and when exported by zotero, it results in a RIS file that is not imported, but I don't see anything wrong at first glance.
Google Scholar.ris.txt

To Reproduce
Steps to reproduce the behavior:

1. Upload attached broken file
2. Observe result

Expected behavior
Failed import, not a hanging import task.
