Photoshop Elements 2020 - crashes and/or refuses to upload photos macOS Catlina

Hi

I am running Elements 2020 on a mid 2015 IMac, version 10.15.7 on Mac OS Catalina.

Initially the organiser and/or photo downloader consistently crashed either before or during uploading photos from a compact flash card.

Things then got progressively worse eg I could eventually download the photos to the computer but it then stopped deleting the photos from the CF card eg it crashed at that point meaning I have to manually delete the photos (dont want to format card as some past photos I want to retain on it).

Now I am having difficulty with the photo downloader even detecting the CF card eg it says "no device found".

Any pointers gratefully received as this Adobe software is driving me slowly demented...

Thanks

Richard
