OM-1 photos cannot be added since upgrading to LR 6.5

Since I upgraded my LR software to 6.5 a couple of days ago on macbook pro running apple silicon and Ventura 13.3.1 I cannot add photos either .jpg or .orf. I don't get any error messages, just a solid triangle with an exclamation mark for each file.  I've tried different cameras and old files that I have previously been able to import and they don't work either. Other than some .jpg files I exported from LR.  But I cannot import files that I exported as originals from LR??

Anyone else having this issue??? 
I can add to my iPad and then hopefully sync to my macbook, but internet is really poor at Airly Beach with a big Telstra upgrade so that isn't working either on my hotspot at present..
