Deleted important file, Mac won

Hello. I was using the Find Any File app to delete any and all files with the name "native instruments" in them and i accidentally deleted a whole folder in which a plist was contained, as i had pressed shift when selecting instead of command. I deleted immediately so I couldn't cmd+z. After this, multiple things weren't working (spotify would crash as soon as i opened it, preferences wouldn't allow me to click on Users&Groups, but i cant remember the error it gave me and i when moving an app to the applications folder, the username field in the "Enter admin credentials" popup was blank and if i entered my correct ones it would still not recognize the).

The only thing i recalll of the files being deleted was that one of the folders (probably the parent of all) started with a dot, and that one folder had random letters and numbers. Possibly also one called cp but i wouldn't be sure.

My dumb *** decided (instead of updating through system preferences, which i could have done) to reboot. Upon logging in, the progress bar started fast but got super slow towards the end and finally completely stopped at 100%, i left it for half an hour and nothing would happen.

I tried reinstalling MacOS through the Recovery partition, and the first time it gave me the error "Could not create a preboot volume on the APFS partition". I then booted into Windows, which is installed on an external drive and tried searching for solutions. When i went back to the MacOS recovery, upon running diskutil list I discovered that i now had a preboot partition, in the same disk as Macintosh HD and Macintosh HD Data. I also had up to 23 disks named "untitled" which were small in size.

This time when trying to reinstall MacOS, I no longer had enough storage (i was missing 8GB). After scrambling the internet, i went back to recovery and discovered I had a Time Machine snapshot from a few hours prior, but apparently by the time the snapshot was created i had already messed up, since after restoring (which took less than a minute) i was back to square one. At least now I had enough space to try reinstalling the OS again.

This time it worked, went all the way through and rebooted automatically but into a completely black screen. The computer is on but the screen is black. If I touch the computer, it is hot which i believe means its trying to do something. I held down the power button to force shut down and here's what i then tried, based on what i found on the internet:

• Resetting NVRAM/PRAM and booting normally. Would get stuck at 100%
• Booting to safe mode but wouldn't ask for a second password and it would still get stuck at 100%
• Resetting the SMC. Same error.
• Booting to Diagnostics Mode but after scanning it said that everything is fine, as did all attempts to first aid Mac HD and Mac HD Data.

I then went back to recovery and restored to the snapshot again. Fast forward to now, I reinstalled the OS again with no errors but my computer has been on the black screen without doing anything for about 45 minutes. I should mention that after the first time i got to this screen, when holding option during boot I could see a "macOS Installer" drive I could boot off of, and when trying, I was back to the black screen.

What the heck am I to do now? I cannot reset my drive, I have way too much stuff I haven't uploaded to a cloud and my latest backup is 105 days old due to corona keeping me away from my home drive.

If there is any way to backup all my data to an external drive (about 100gb), suggestions welcome, I will be buying a hard drive possibly today. Also, the file I deleted is most likely a preference file.
