Unexpectedly, instead of the calendar page, I get the message "Attempt to modify property "datamodel" on null".

What could have caused this error and how to fix it?
Can I have a hint?
Please upgrade to JEvents 3.6.52 + if it doesn't show in the update manager then download and install it manually.

I have the same issue.
And I think, that I have the latest version --> JEvents 3.6
Joomla 4.3 do not offer an update for JEvents

Any suggestion?

Thank you very much
