I have upgraded to Mojave and also to latest LR and PS and now I can not stitch any panoramas in either LR or PS. It shows in the preview window but just hangs on creation. Also LR constantly has to force quit as it just starts pinwheeling randomly
I think that this is one for the support team as I reckon it's got confused between different versions. Adobe's updater leaves all sorts of baggage behind and doesn't uninstall any previous versions etc. I had awful issues with Bridge and had to remove all instances before I could get it to work correctly.
