My backup save

ALL MY BACKUPS DON' WORK AAAAAAAAAAAA

I TRY TO PUT IT IN ANOTHER FOLDER AND IT DOESN'T WORK, I TRY TO PUT IT IN DISCORD,I TRY TO PUT IT IN THE FREAKING TRASH BIN AND IT DOESN'T WORK, EVEN THE SAVE FILES I DOWLOADED DOESN'T WORK THIS IS MY LAST RESORT AAAAAAAAAAAAAAAAAAAAA

EDIT: Just to clarify, The save I'm trying to replace works as intended, everything is normal with the exception that it can't be replaced
