APDL crashing when trying to solve with multiple boundary conditions

      I am using a very coarse mesh since finer meshes also cause the software to crash, and the software will not run when two separate boundary conditions are added (I'm using a wing so the boundary conditions are that the nodes at the wing root are constrained in all DOF and then I set all the nodes with a no-rotate condition). When trying to solve this ~1000 node problem the software would crash. Are there any easy fixes to this probem? I've turned Uthick routine off. The version of Ansys is 2022R2, but 2023R2 also doesn't work.

      Perhaps start with some proof of this 'crash'.  A screen shot of the output.  Or of any/all warning or error messages.  Is the behavior really a crash or does the solution just not converge?
