Try the model Peter attached.

I think what Peter said is a good suggestion if this model does not work, because we have not seen this issue and can not reproduce this.

Before doing that though can you try making a new example/project, and the save it in a folder say under your user account so e.g., C:\Users\evgenii., and see if that works.

Finally if that does not do it, in the static analysis use/insert an apdl command object:
rescontrol,linear,last! Turn on restart files due to future eigen analysis intent

Let us know how it goes
