Just today I was attempting to install something through the terminal and noticed that running 'sudo apt update' gave me a strange error I don't normally see. In an attempt to fix this, I ended up down a rabbit hole which resulted in me causing an issue with the sym link for/usr/bin/python, which I then believe I fixed by pointing it to python3.10, though the original issue persisted.
The issue following one of the various solution is shown below, and so far has occurred with every other solution on every post with the same or a similar issue. I have not tried every single solution inexhaustibly, primarily to avoid making a worse mistake and as a result of reading various people saying such and such solution caused such and such issue, though I am at this point out of things to try.

I don't have any real idea what information would be relevant to include, so if additional information is required, or a proposition is made for attempting a previous solution and detailing the outcome, I would be more than happy to oblige. Currently the changes to sym links I have made in an attempt to resolve the issue is as stated above with python, making a sym link from /usr/bin/python3 to /usr/bin/python3.12.2, and making a sym link from /usr/lib/python3/dist-packages/apt_pkg.so to /usr/lib/python3/dist-packages/apt_pkg.cpython-36m-x86_64-linux-gnu.so. I believe I used the correct order when executing these commands, as I checked the results subsequently, but again I would be open to test anything out.
EDIT: The suggested duplicate/ solution "https://askubuntu.com/questions/1242009/modulenotfounderror-no-module-named-apt-pkg-appears-in-various-commands" does not fix my problem, with the accepted solution giving me:
