Python: TypeError: required field "type_ignores" missing from Module in Jupyter notebook – Debian

I have been having issues with my jupyter notebook for a few days. I didn’t fix them at the time but have decided to now. Earlier whenever I executed anything in the jupyter notebook, It showed a lengthy list of errors in the terminal(not in the notebook). I tried the same in jupyterlab but again, the same error. I upgraded my ipykernel and somehow it started working again.But this time it only executes a few statements such as print(hello world)

I tried using a few other things like this:

a = 1
b = 2

a+b

But it gave me this error:

TypeError                                 Traceback (most recent call last)
/usr/lib/python3.8/codeop.py in __call__(self, source, filename, symbol)
    134 
    135     def __call__(self, source, filename, symbol):
--> 136         codeob = compile(source, filename, symbol, self.flags, 1)
    137         for feature in _features:
    138             if codeob.co_flags & feature.compiler_flag:

TypeError: required field "type_ignores" missing from Module

I tried other things like importing a module but the same error. I am using Ubuntu 20.04 with python 3.8.2. What do I do? Here are all the installed libraries:
