Version

11.0.1

Bug description

We very recently upgraded our GLPI version (From 10.0.19 to 11.0.1) and we started getting a weird error that prevents us from using GLPI to search for computers in our database :

An unexpected error occurred
Return to previous page
Top of the page

I believe this only started happening ever since we installed the newest version, and the migration seemed to have happened without any issue as well.
We typically use GLPI Inventory with the GLPI Agent installed on all the computers we have.
It seems that once the issue occurs, the page still refuses to display properly until the browser is completely cleared of its cache, even when removing all the search terms.

Relevant log output

There doesn’t seem to be anything relevant to this issue in the GLPI logs, but I noticed some errors in my browser’s console that could potentially help figure out what’s going on.

There is also this error that pops up in php-errors.log but it might be completely unrelated :

Anything else?

It seems this issue only happens very specifically with "computers.php". I can try things around or give more details if required. Thank you very much for your support.
