This troubleshooting page in our Documentation site will help you fix this problem.

We explain you how to identify the root cause using the ui-designer logs.

This issue appears when some artifacts from the UI Designer got corrupted in your git repository, so we tell you what happens and give you a solution if you are using Git in Bonita Studio or not.
