Hello @pawan-khade, thank you for reaching us.

Could you share which versions of CKEditor 5 and MathType for CKEditor 5 are you using?

CKEditor 5 did a release recently, v46 in which they updated this dependency. Yesterday, we updated our packages to be compatible with their latest release, so knowing which versions you are using will be a big help for us to solve your problem. Thanks!

"ckeditor5": "^44.0.0",
"@wiris/mathtype-ckeditor5": "^8.11.1",

Hi @carla-at-wiris,

Thank you for reaching out promptly to help address the issue.

I've specified the versions I'm using:

CKEditor: v46

MathType: v8.13.3

Unfortunately, a critical functionality in my application is currently not working due to this issue. I’ve also upgraded both CKEditor and MathType to the latest versions mentioned above, but the problem still persists.

Could you please assist further with this?

Thanks in advance!
