SD card badly corrupted

Hello, I tried every single methods to fix my corrupted SD card but nothing works. I tried chkdsk command method but it said "cannot open volume for direct access" than I tried disk management method, but disk 1, which should be my SD card, didn't even show up and it said 'no media'. When I try to format it on my PC it says there is no disk. Whenever I try to access the SD card it tells me to insert the disk, but the disk is there and if I open 'this PC' tab I can see the card mounted. If I try to insert my card into my phone it doesn't even recognise it is there; it just says that SD card is not inserted. Pls help me! I really need to get my files back from my SD card.
