Windows 10: MicroSd Card - cannot format but can read

Strangest thing I have 128gb MicroSD card.

Ive tried formatting in Windows 10, Disk Mgmt, Diskpart, AOMEI, EaseUS, SD Formatter, Android, old camera, Roku - no matter what I do it does not format

It is currently exFat, I can still view the files. I have tried multiple adapters It is a SanDisk Ultra microSDXC

The weird thing is via Windows I can delete and create files on the disk without errors. Once I remove the card and reinsert, the changes are gone (what I deleted is there, what I created is not)

I would think it was write protection but wouldnt that produce an error and there is no write protection switch on the microsd card itself afaik , only only on the adapter and I tried different readers and adapters

Lumia 635 microSD card issue.

We purchased 2 Lumia 635's here a couple of months ago, and for the most part they have been working flawlessly, however, my fiancée's phone has one slight bug that I can't wrap myself around.

For whatever reason, her microSD card cannot be read by the phone, nor can it be read via USB cable.

Here is what I have done to troubleshoot:

• I swapped microSD cards, and I could read hers on my phone, but could not read mine on hers.
• I read my microSD card on my W8.1 computer both through USB cable and through the reader with no problem.
• I read her microSD card on my W8.1 computer both through USB cable and through the reader with no problem.
• I formatted her micoSD card on my W8.1 computer, and it worked fine.
  • When I inserted it into her phone, it did not see it.
  • When I tried to format it on her phone, it did not see it.
  • When I tried to look at Storage Sense, it was grayed out.

Any ideas as to what could be going on?

Thanks!
