Block error in template modification

Hello, I saw that my problem has already been cited in the community but the procedure does not work for me. When I want to modify a template, it tells me an error for some blocks (listing form, title and page description).
I deactivated the other plugins but that didn’t change anything. I also tried by importing the demo. Thank you in advance for your help
