Pdfs won't open in iPad after iOS 18.0 update

Pdfs won't open

I updated to iOS 18.0 three days ago and suddenly all my newly aquired PDF files flicker when I try to save or open them. These that already are in iCloud on my ipad will open but as soon as I touch an area to copy text the same thing happens.

The behavior occurs for a PDF attachment in email, a PDF download a PDF already in iCloud Files. Lots of flashing/blinking and then turns to a white screen that shows the file information instead of showing the actual pdf on screen.

Had hoped the 18.0 update last night would help but it did not.

So disappointed. Is there any known work around until Apple can get this fixed?
