So he has a line in there somewhere that is not correct pointing to another repo. Or he has not updated his cache since removing one it is the only way it can be doing it. Everything here shows it will do as it is supposed to on a stable system and install the programs.
My first guess would be that some packages were installed without the use of apt. That's easy to do, and not uncommon. It's not always the best idea, but people do it. Usually it's harmless, but now and then it can result in unintended consequences.
I tried reinstalling python3.7 and that didn't work. Manually installing the dependencies in one command like suggested doesnt work either:

apt install blueman python3-gi gir1.2-gtk-3.0 gir1.2-gdkpixbuf-2.0 gir1.2-glib-2.0 gir1.2-pango-1.0 gir1.2-notify-0.7 python3-gi-cairo gir1.2-appindicator3-0.1

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
gir1.2-glib-2.0 : Depends: libgirepository-1.0-1 (>= 1.45.4) but it is not going to be installed
python3-gi : Depends: libgirepository-1.0-1 (>= 1.44.0) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
You're probably right, I must've installed a package outside of apt that broke everything. One thing I don't understand though. Everything started because I had python3.8 instead of python3.7. But after manually installing python3.7 shouldn't that fix the issue?
And question number two, can I restore this Debian to it's original state (without package conflict) with an apt-get dist-upgrade?
You have other packages and libraries mixed in from other repositories. I wouldn't even guess how many. I suggest using aptitude and letting it suggest solutions. Apt is not good at fixing things in this situation.

Install aptitude and let it try to fix the munged system. I don't think a simple update will fix things, but you can try it.
Hi! Just to update the solution. Aptitude seemed to resolve the issue. After declining the first suggestion (to keep everything as it was), it suggested to remove gstreamer1.0-plugins-bad and lib-gstreamer-plugins-bad1.0.0 and to downgrade libglib2.0-0 and libgstreamer-plugins-base1.0-0. This allowed me to install blueman and everything seems to be ok. Here's the log:
