Comsol crashes only when computing "solid mechanics"

I have a problem using COMSOL Multiphysics.
When I computing a "heat transfer in solid " model, there is no problem.
However, if I computing a "solid mechanics" model, the COMSOL crashes and "hs_err" file comes up.
My computer RAM is sufficient to compute the models(16GB). And computing the models in another computer makes no trouble.
Although I reduce the number of meshes, COMSOL still crashes, even faster.
In addition, what I found is that CPU does not worked after I clicked the "compute" button.
Right after I clicked, the usage of CPU rised up to 33% and didn't rise any more. And then CPU usage decreased and, at that time, COMSOL was shut down.
My CPU is AMD Ryzen 5 3600 My GPU is Geforce 1660 super MY RAM is 16GB
Please tell me how to fix it.
