How does one downgrade pycharm version -- ideally without uninstalling pycharm or keeping multiple version?

I'm currently facing an issue with the latest version of pycharm (detailed at the end). Due to that I want to downgrade pycharm version from 2023.4 to 2023.2 or 2023.3 such that it disturbs my computer the least e.g., not losing settings, projects, deployment configs, avoiding keeping multiple version of the idea in my computer to avoid confusions, etc.

How does one do this? I couldn't find anything on their website or the settings menu or google.

Concrete context:
```
I'm trying to push to my servers on save and manually. It doesn't work. I updated to version:

it doesn't work. If I go directly to the SSH configuration by clicking the ... button next to the me@uni.edu then try to connect from there using Test Connection it connects. But one window before the ... the Test Connection doesn't work. Push on save doesn't work. Also, manually pushing doesn't work. There is a fatal bug that wasted a lot of time for me today. Needs to be urgently fixed.
