I am beta testing MSFS's SU15 and a few of us in MSFS forums have noticed that SU15 "breaks" FSRealistic, particularly with not being able to tell what aircraft you are currently flying, which then breaks the ability to find public profiles others have shared/uploaded for that particular aircraft.
Affected aircraft that I've personally tested:
Fenix A320
PMDG 737, 738, 739
Hey captain, please refer to the following: https://rkappsus.wixsite.com/rkapps/forum/fsrealistic/fsrealistic-v2-2-1-public-beta
Thank you, we are indeed working on a fix for that.
Several MSFS'ers are also stating the same issue as well as FSRealistic causing CTDs in SU15 beta
