Microsoft Edge "Save as" function not working for pdfs

Every Windows 11 update since April has caused the Edge PDF writer to malfunction on my computer.  Once the update occurs, the Edge PDF writer will allow all the tools to work, but refuses to save anything.   Before I start hearing all the suggestions such as disable new PDF viewer, clear cache, disable acceleration, etc.  believe me, I've tried every 'remedy" that has been previously posted.  The only thing that has so far is doing a Windows 11 rollback restore, which gets rid of all the updates since April 2026.  I am a teacher and heavily rely on Edge PDF.  NO other program will do with such ease and simplicity what Edge PDF viewer does.  It allows my student to do homework directly on PDF files and for me to grade them.  I am a huge believer in keeping Windows constantly updated, but because of this problem, I've finally resorted to disabling the Windows Update feature.  I cannot continue to have this problem occur every time there is an update.  Anyone else experiencing this and, aside from all the "fixes" that date back to 2023 that have not worked, if you know what else might be causing this, I'm open to suggestions.  Thank you!
