Did I damage my MBP mother board / logic board?

Two tight screws in my Macbook Pro retina are stripped after I tried to remove my bloated battery. They were the only ones that have this problem. They have never been unscrewed as far as I had the MBP. In my attempt to resolve this, the socket, or the holder of the top right screw came off from the board. I wonder if I ruined the Macbook's functionality. I can't fully test the computer as the CPU is extremely slow, probably due to the deteriorating battery. The only thing I did was check if it still turns on. It does. Can anyone tell me if there is a circuit on the other side? Or if I damaged the board? Apologies in advance I am not a native English speaker.

Referring to the pictures, the red tape shows the screw location. The white stuff are just foam tape residue.

It appears you only snapped off the stud which is just glued to the board! I wish Apple would use thru-hole mounts as they just hold up better. Apple tends to make repairs harder in how they secure screws using thread lock, You need to use heat to soften the bond or a solvent (if you can get it in). The next issue is having a good driver and bit! Many people use too small a handle and/or use a worn or badly made bit. the most important is pressing down with enough force the bit doesn't slide out as soon as it does the first time it becomes harder to get the screw out.

Can you get the onboard diagnostics to run? Mac startup key combinations did you get any errors? Often when the system is sluggish tells me the system is in CPU safe mode lowering the CPU's clocking and often boosting the fans RPM's

Thank you! Your answer gave me such a relief. The CPU is no longer very slow and I can run programs. The fan is still running at full speed though, and resetting the SMC does nothing. I am getting a replacement battery soon and will see if the bloated battery is causing the problem. I did start up the computer in safe mode a month ago when I tried to upgrade to Monterey from Mojave. But it always got stuck and I quit the upgrade. I don't know if some system got overwritten or something. I agree Apple is terrible when it comes to self-repair. If I hadn't bought all my work related software for mac os I would've just gotten microsoft laptop. I'm glad there's the ifixit community. Oh, I used double sided foam tape to protect nearby components when I tried to force the screw out.
