When adding a Joomla Custom Field "mediajce" media field, while already having a Joomla Custom Field "repeatable media" there's a conflict.

The Lightbox shows the following error (When I click on the Joomla Media Picker):

0 - An error has occurred.
Invalid controller: name='mediafield', format=''

Console Error:
Failed to load resource: the server responded with a status of 500 ()
https://DOMAIN.com/administrator/index.php?option=com_jce&task=mediafield.display&fieldid=jform_com_fields__pdfs__pdfs0__File

Yes, I'm running v2.9.4

Ryan, I was able to only use JCE's media custom field, and I'm not having issues, but while building a layout I noticed the issues and I thought I'd let you guys know :)

I updated to joomla 4.0.4 and have the same error with image upload under "images and link". I have also a jce media field and this works. If I disable this field, the "images & links" upload works again.
Any idea?

Just for information: I deinstalled JCE and reinstalled it, and now it works!
