Solution

This issue happens in build distributions when the proper panel file is not included in the distribution. It can also happen when the distribution is corrupted. To solve this issue, follow the next suggestions:

    • Make sure any .uir file called in the code is also added in the Destinations section. .uir files are added by default on new distributions.

  • To solve potential issues due to corrupted distributions, recreate a new distribution using the same base files.
