Can you explain what this means? Did it not load? Did you get Robot Code on your Driver Station? Did it enable? What error messages do you get on the Driver Station Diagnostics box?

To me this indicates that you have a short between 5V and GND on one of the PWM cables you unplugged from the Sidecar. If this is true, with everything plugged in, I would think that the 5V light on your Sidecar would not turn on.

There are no warnings on our bot or error messages, just random stuff going on.

We tried sample code given by FIRST and ran it on the robot.

For some reason, everything works now, but we do not understand why.

Thanks for all the help everyone!

I echo the battery posts... (no pun intended)
Make sure you have a fully charged battery that has all cells working.

I have seen really funny things happen with batteries with a bad cell...

You need to check the voltage under load to determine whether it is good or not..
