Hi,
1. This error will appear during checkout: internal server error.

Then I found this file.

Then added this code to this file.

This problem is solved, but I am not sure whether this method is correct. Do you have any other methods?
2. This error occurred while editing Product categories: https://prnt.sc/t7v62f
Is there any solution? It has nothing to do with your template.
Thank you
