Error message when trying to export tifs

[bill6C15]

I do not see an answer to this issue on the forum...

Recently, LR CC stopped exporting tif files on mac M1. I used to be able to select and export as many as 100 or more tifs and export to my external hard drive. 

Troubleshooting, I cannot even export one tif to external hd or even to desktop. I can export jpgs. 

any suggestions?

What does the error message say?

At a guess, could it be having trouble accessing the Cloud, if it's trying to access it to

export a full res tif (it may not need to for a low res jpeg).

Says...Error uploading images. 

Worked flawlessly and then it didn't work at all. Only jpgs now. 
internet/wifi not the issue.
