Hardware Nintendo Switch Locked my SD Card

[Niplex]

So, I was flashing OS on my SD Card (SD is Genuine), but before that, I backed up "Nintendo" folder, week later (now) I wanted to format it and copy my backup from desktop, but after formatting it with FAT32, Nintendo Switch decided that it want to reformat it to exFAT, so I allowed it, and I wanted to copy backup again, but now Windows thinks that my SD Card is write-protected, also it isn't dead because Switch still can save Photos, Videos, etc. Does anyone know how to disable it?

I know my English is bad...

Edit: I formated it using macOS and it is working now!

My switch has done this with two of my micro sd cards, one being quite a pricey one. What I've found is try not remove your sd cards from the reader too much as this can not only damage the card but the reader itself. Read only is usually an indicator of a dead sd card if windows wont let you modify or copy files to it.
