My test does not recognize mapped objects (v15.45.31.7)

I have a project that unexpectedly when run doesn't recognize the mapped objects. I've tried several scripts that all worked perfectly, but now it always waits for the first mapped object it finds. I don't know what could have changed, I'm using version 15.45.31.7, I have the same problem with chrome and edge. What can I review? I don't know what I should look for. I have read other community posts with similar problems, I already went to File/Intall extensions/web.

I am sure that I have not made any changes in the Name Mapping and that the interface was the same in which my test worked well.

Thanks!
