Solution:

Follow the prompts in the source file path to find the corresponding file to open, and then delete the node that reported the error. It is possible that one error may be deleted, and another error will be reported. The deletion will continue until no error is reported.

The following content is the content near my error report. The red part is the two nodes I reported the error. I deleted them one by one, and the. NET MVC project can run normally.
