"PS Does Not Recognize This Type of File"

[mattsnell]

When I updated to OS Catalina, I immediately started having strange issues opening CR2 files from my business network.  There doesn't seem to be any rhyme or reason to when it works or doesn't.  I've even had situations where two consecutive shots, taken 1 second apart (basically identical files), where one opened normally, and the other gave me this pop-up window saying "disk error." (screenshot below)  

The CR2 files are from at least 3 different canon models (5D-II, 5D-III & 6D-I).  They will always open & preview properly in Bridge. But then opening from Bridge to Photoshop will give me a different pop-up "PS does not recognize this type of file" (screenshot below). 

If I copy the files to my computer hard drive, I am then able to open normally (either thru Bridge, or directly from finder window > into Photoshop) 100% of the time.  So it has to be something connected with the network. It's just very confusing that some files open and some don't. and there's no more info I can find about what specifically is the problem. 

I do have the most up-to-date versions of Photoshop, Bridge & ACR. 

Thanks for any help, 

Matt

Does it happen in the previous Photoshop version 20 or just this latest one?

It started happening when I updated to Catalina & PS 20 several months ago.  (I needed to handle new iPhone HEIF image files, which was reason for updates).  Had hoped maybe after another round of updates with OS & Adobe, it might sort itself out, but problem hasn't changed with update to PS 21.1.3

I did look through the Catalina compatability issues, which reminded me I also sometimes have PSD files freeze at 99% while saving to network drive, rendering them garbage.  Can't open them. Can't cancel save process. (best I can seem to do is go look for previous version in Time Machine if it was a multi-day project).  But it's too risky to let that happen and erase even an hour's work, so I'm in habit of selecting raw files in Bridge, copying them to my iMac boot drive, editing from there, and then copying back to network when I'm done (which is obviously not ideal, but no freezing occurs when I only work from Mac).
