Stability issues since update with ACR and Bridge

Today I updated to the latest Photoshop, ACR and Bridge.  Previous install was great.  I believe I had not updated in a year, but it was super stable.  Also, the Adjustment Brush in ACR is super laggy and before and after.  I'm running on a MacBook Air and I had no problems working on my D850 files until today.  Anyone else having issues?  Any suggestions?
