I have these errors on the page that I really don't know what they mean and I have problems with some modules that don't look good or don't work well.

Does anyone have these problems or have you fixed them?

Thanks for your help

disable JS CCC, and then check console again. There should be more user friendly stacktrace

Thank you very much for your help, I deactivated what you told me and I managed to discover right away that it was a module that was giving problems, I deactivated the module and it works perfectly and without errors.
