Trying figure out what is going on here I did the following procedure:
1. Right click on the component PCB, select Save Copy As
2. Save the PCB component outside of the design/project
3. Open the PCB component and then perform a Modify > Compute All
Results:
Errors appear in the timeline, including some warning for the first sketch in the timeline.
Hypothesis:
The initial sketch is referencing a construction plane or one of the default planes from the root assembly or from another component. When editing the sketches in the component, this is somehow interfering with "orient to plane" feature being able to determine the correct normal position..
I have reported this to development for further investigation into the cause and a resolution, reference FUS-20759.
As a quick solution you may be able to use the steps outlined above, repair the errors and then re-insert the design into the original component group to resolve the issue.
I hope this helps. Let me know if you have any questions.
