Latest Update on JCE 2.9.75 causing problems in editor

Hallo guys,
I ran the latest update for JCE 2.9.75 and since the update the editor does not work in Gridbox 2.17.0.2 in Joomla 5.1.1:
- edit TEXT window does not open the editor
- new TEXT plugins with wording does not show
I have uninstalled JCE for now to make things work.
Kind Regards
Stephan
