If you can provide the following information, perhaps we can provide a differential diagnosis (without the House sarcasm/snarking)

Programming Language
Which CRIO
Pneumatics? If so, how much?
Vision processing? If so, on or offboard via Raspberry Pi or such things?
Drive Train/wheels
Electronics correctly wired, including the dedicated wiring?
What the CSA/FTA/FTAA advised?
When you swapped the CRIO, were the modules swapped too?
Digital Sidecar tested good?
No tripped breakers?

I had a team with similar issues. They were using Java with offboard Raspberry Pi Vision processing, mecanum drive and LARGE 24 Solenoids wired off of the CRIO.
In the end, we corrected the wiring, disabled the Pi, Went to a basic code and swapped all the modules. By then, she was purring like a kitten and rebuilt the code. We didn't open the CRIO or swap it but I think if I had opened it up there would have been some debris in it.

I know it is a lot to ask post mortem but it helps to put issues to bed before St. Louis and the "Off Season".
