Need help!

So today my sd card reader just wouldn't show the right folders, like it's just multiple sounds, pictures, android, movies etc., with most having 0 contents inside. I tried to change it from reverse charge to transfer file/photos but it would revert back and it is correctly detected by the device but again wrong folders with none of my pics, vids, and files inside.

This occurred after my friend plugged it on his phone with a different connector/interface(idk if this helps) and while it worked on his phone when we tried to troubleshoot it didn't when plugged to mine and the rest of the day I spent trying figure out what caused it.

Pls help I'm at my wits end and my pictures and videos inside are priceless, I have tried what I could and none of the solutions I've searched on the internet are working nor applicable due to most of them are samsung tutorials.

Honor X9b 5g and I think it was after an update.
