We are dealing with it now. For some users, it just crashes upon opening. I am able to open the program, but when running an RSA analysis for an equipment tower built using 17.0.2, it falls into an infinite spiral of hell - perform dynamic solution, calculate RSA, clears results, perform dynamic solution, calculate RSA, clears results...
When selecting a floor elevation and trying to lock all other portions of the model - crash.
RISA is now working directly with our IT department to determine what is wrong. Our department has become a bunch of beta testers.
