Update Google Drive and Adobe Acrobat Reader
Updating both apps to their latest versions resolves the known bug that causes the unknown error when opening PDFs.

Once the updates are complete, open Google Drive and try to open the PDF file in Acrobat Reader again.

Frequently Asked Questions
Why am I getting an unknown error opening PDFs from Google Drive on my iPhone?

If updating your app does not fix the issue, you can report it by going to Adobe's official bug reporting forum. Provide your iOS version, app version, a screen recording, and the affected PDF file if possible.
