Edit event error after update

I've updated JEvents to the latest version (3.6.42). Now I get an error when trying to edit or create an event:


0 version_compare(): Argument #3 ($operator) must be a valid comparison operator


It seems to have to do something with the edit form override. The default template works fine. Is there anything that has changed so my template doesn't work anymore?

Edit: it has some the to do with the lay-out override. If I leave the lay-out for editing events empty, it will use the default. This works fine. If I change anything to the lay-out, i.e. just adding a x, the lay-out is broken when rendering.
This issue apparently has to do with PHP 8.0 or 8.1. I am getting this error message too when creating a new event. The temporary solution is: switch back to PHP 7.4

Kind regards
Chris

Please try this version - it resolved the PHP 8.x issue and will be the basis of a new release tomorrow.

Does not work here with PHP 8.1. Error
0 version_compare(): Argument #3 ($operator) must be a valid comparison operator


With PHP 7.4 it's ok.

Can you enable Joomla debug mode so I can see where the error is being called? I had found one potential problem area but it looks as though there may be another

I have got same error on PHP 8.1. Using Jevents 3.6.42.
When going back to jevents 3.6.39 I can edit and make new events without error and still using PHP 8.1.

I'm really embarrassed to say that the package I uploaded yesterday was built BEFORE I'd fixed the problem - more haste less speed . This version definitely resolves the issue at this point

Can you enable Joomla debug mode and give me a screenshot of the errors you get please so we can see what file and line number is causing the problem.

I'm sorry for being so slow to reply to this - it didn't appear in my notifications for some reason

I've made this post private so you can attach a screenshot without the content being public
