I get the folowing error when trying to open Sourcerer

Joomla 4.3.4
PHP 8.1
Regular Labs updated - sourcerer 10.0.0

All the existing modules using sourcerer works, but I cant make new ones.

Sorry my late reply, Ive been busy with other work. The error shows before I insert any code. So it cant be the code itself, or do you mean in an earlier use? Here is the errors. I dont see anything relevant. Do you?

Thank you so much, that worked.
