Yes I have similar issue
Provide extra information to complete the original description of the issue:
I have them after SU13 ,all updates installed (worked with SU12 ) , I think it is correlated with the quantity of files . I did a full new installation , I think was above 450 files , when deleted one of the addon from the same airport from different providers , new addons for installation appeared , it was Reno Race and Top Gun. When downloaded them and go to play the sim , crash appeared . When restarted the sim no access to market place , all content was missing and permanent check of content was running.
