Hello Haoris,

I have a couple of questions to help resolve your issue:

  1. Have you tried deleting your immediate & saved folders?
  2. Was this project recently updated from an older version?
  3. Could you upload your full log?

Based on the logs you have attached, you appear to have a function that is throwing errors, specifically a function called ‘UpdateSelection’. Could you check for any errors in this function?
