Background
I've been using PyCharm with Conda for up to two years, but until a week ago, it was performing normally. But after I use python 3.10 virtual environment once, the following problem happens in any environment(3.8; 3.9; local and origin). However, the code runs successfully and everything works fine in VSCode.
Description
The editor shows 'unsolved package xxx', but the package has shown in 'External Libraries'.

After my observation, it seems to be unable to solve models that are imported in any __init__ file. If no __init__, it will solve successfully (like Adam in torch.optim).

I have already tried followings:
- File -> repire IDE
- File -> Invalidate caches
- Reinstall; Install EAP; Install Pycharm 3.1
- Reinstall conda environment
But the issue still exists.
