I understand your concerns but as of now there are no updates from HP's RnD Team or from Apple. Both HP and Apple are working on this issue to get it fixed soon

I Am An HP Employee

An efficient work-around that has not yet been mentioned in this thread (I think) is to use "scan to email". For me, this is better than the HP Smart App, because the latter requires me to give the scan instructions on my laptop
With "scan to email" you give the instructions (and turn the pages, if required) on the HP scanner itself, just as with the Easy Scan. You can leave your laptop or other Catalina machine where it lives. (My HP multifunctional is in a different room from my own workstation.)

I'm getting the same error message on Mac OS Catalina when using HP scan, however I found a workaround by going to System Settings/Printers and selecting the "Scan" tab and pressing the "open scanner" button. This opens a different scan window where you can still select the flat bed for scanning.
