Issue with running my python code after updating anaconda

Hi, I'm writing code using python (anaconda -spyder). my code was running and every thing was ok. but yesterday I updated the anaconda and the code stop running (I got the message: ModuleNotFoundError: No module named 'mymodule'), despite the fact the my mymodule found in the same place (same file that I'm running) and sys.path. I didn't change any thing In the code).
