  Hi,
  I was using lumerical 2022 R2.4 and recently updated it to 2023 R2.3. After that, it crashes when I open a new or old project in varFDTD. Closes the project without saving. I tried to remove all folders and install old and new versions, including 2022, 2023 and 2024. But the problem still continues. Can you please help me, I couldn't find any cases like that online. I am a commercial customer so you can also reach me via email.
  Best Wishes
