Dynamic link media server failed to launch
It seems that in the past 4-5 months every single time I go to use Lightroom I find something has 'broken'. As a result I'm spending more time 'fixing' LR then using it for what I bought it for and it's getting very annoying.
Anyway, rant over. Two weeks ago I was using LR and everything was working correctly, then last week I was on holiday and so my iMac was switched off and nobody has used it or LR until I launched it yesterday to download all my photos. All my photos imported into my catalog fine, it did fail to import the videos I'd shot which were .MOV files but LR never seems to be able to import them and I don't really need video in LR so it's never particularly bothered me.
I was able to edit and organise the photos without problem but when I try to do a slideshow I then get the message "Dynamic link media server failed to launch" after which the play button is greyed out.
I tried uninstalling and reinstalling LR. No difference
I tried a solution I found on here where you open a Finder window and Go to Home, make sure you have read/write access, unlock it and then apply to all enclosed items. When I did this, relaunched LR and tried to play the slideshow i didn't get an error message but the screen would just go black for 20 seconds or so. After several times doing this I then got the same Dynamic Link media server error message.
Tried repairing permissions on my system drive. No difference.
I'm running OSX High Sierra 10.13.4 with LR Classic CC 7.3.1
