LrC locks up in Develope mode

[Mokiron]

Running Mohave 10.14.6 on MAC Pro (Mid 2010)

Memory 32GB   Startup disc SSD   Graphics AMD Radeon HD 7950 3GB

Data storage on internal 6TB HD with 4.36 TB available

No error messages noted

Problem occurs in Develope mode with most activities,especially cropping.  Most times I see the "spinning wheel", then the computer locks up. The mouse will not function and I can not back out of the program

via CMD-OPT-ESC.  I have to turn off ane restart the computer to procede.  Any help or suggestions would be appreciated.

You may need to roll back your LrC version

Adobe appears to be having a major problem in MACOS.
