ship immobile when attempting vectoring thrust

I have an unmodded save world where I am working on a small grid prototype cargo ship. The main feature of that ship is meant to be thrust vectoring pods on the sides, however the ship seems to be frozen in place and the convert to options are greyed out. I made a copy of the ship without thrust vectoring, and it moves without a problem. I am unable to discern if the problem is a bug with SE, or an issue with the thrust vectoring script. When accessing the programmable block, I see a message that says everything stopped. Performance mode. This is new to me as I have not had a problem previously with this script. Noted symptoms include the following so far:

-Ship is frozen in place despite not being listed as a station. Thrusters activate but speed does not increase. No change with additional thrusters

-Thrust Vectoring script is added yet does not seem to recognise the rotors. Rotors are not locked and remain in original position

-Inertia Dampners non responsive to manual command (Z) and revert to not being activated in the cockpit

-Ship will respond to gyro movements

-Ship is powered and on

-Reloaded and recompiled script. No change

-Copied and repasted ship. No change
