CST - Frequency Domain Solver (TET) terminated abnormally

Hi , I wanted to reach out regarding an ongoing issue I've been facing while using CST , About a year ago, I switched to working on a PC with CST Studio Suite installed on a Windows Server setup. However, I've been encountering intermittent errors that have become quite frustrating to deal with. To make matters worse, there are times when the meshing procedure gets stuck, making it even more challenging to proceed.

I'm curious if any of you have faced similar issues or have any insights to share based on your experience.
