" Can't delete files " error on Lg v20

[Android Central Question]

Never had a problem with anything pertaining to my SD card and one day I go in to delete some files and I get this error message. I stayed up all night reading every article I could find on how to fix it.... And yes, I did the check disk thing. Nothing works. My phone won't even let me format it. Idk what to do and I would like to try to keep the data that's on the card. Can anyone help?
