Hi there!
Sorry for your experience.
I have checked your backend and found out there were helix3 framework too: https://prnt.sc/w_imZQt1eUvX
Helix Ultimate and Helix3 are two different frameworks from us and not recommended to use together in a single site at a time. Kindly uninstall all instances of Helix3 from your site. And then updaate all extensions.
Due to language barrier, I could not understand what types of page is bind to the 'Jobs' menu that shows the error. Will you let me know?
Best Regards
