I am trying to push my app with practically zero changes, just added a file that isn't involved in the app for now. Yesterday the app worked fine but now when I try to push the new version I get this error:

The app should be a telegram bot, and it worked for months until now, and I just can't understand why it isn't working on Heroku, but it works for me. I can think about PyCharm adding libraries to my requirements.txt. In fact when I use:
from telegram.ext import something
PyCharm underlines telegram telling me to add it to the requirements, but the actual library name is python-telegram-bot, not telegram. So maybe PyCharm added the name to the requirements and Heroku installed it, so when it says ImportError: cannot import name 'Update' it's actually looking for it in the telegram library, not in python-telegram-bot. Now I removed the library telegram from requirements but it still doesn't work.
It sounds strange to me, but this is the only reason I could find to this problem since the program runs on my pc, and the code in File "costanti.py", line 1 didn't change, and also because the problem comes from the library files.
