PS SD card writable status doesn't update when actual SD card status changes

[paynterf]

Description of the bug

I inadvertantely inserted an SD card with read-only status set TRUE. PS correctly told me that it couldn't write to the card. So, I removed the card, changed the read-only status to FALSE, then re-inserted the card. Unfortunately, PS still wouldn't write to the card. I confirmed that I could write to the card with File Explorer. The only way to get PS to write to the card was to quit PS entirely and relaunch it, thereby losing the print setup unless I first saved the project.

Project file & How to reproduce

In PS 2.9.0 with a print project loaded, insert an SD card with the write tab disabled. Slice the project and select 'Export G-code'. Select 'Save' in the 'Save G-code file as:' dialog. You will get an error saying PS can't write to the card. Remove the SD card, enable writing, and re-insert the SD card. Try saving the file again - you should get the same error even though the card is actually writeable.
