Files created in Blender 3.0 aren't expected to work 100% in Blender 2.93.1. As such this may not be considered a bug.

Will wait for a response from developers.

I have that issue too when port back rigs made in 3.0. to 2.93
In the meantime, You could fix it by going to the armature edit mode and select the bendy bone and reset its Scale In and Out like in your 3.0 default is 1

Thanks for the report. But while we try to not break forward compatibility in general, forward incompatibilities are not handled as bug reports.
