Hi. We have recently upgraded to D10 with v3.6 of Field Group. I believe we are experiencing the same issues as described above.
I can confirm that in our case the error appears to relate to a performance -> JS aggregation issue that clearly encapsulates the JS from this module. Disabling aggregation fixes the problem of the tabes not rendering correctly.
It looks like Drupal is erroring/failing to aggregate a block of JS. I've only just started investigating, so need to dive a bit deeper into the route cause.
