I keep getting a lot of errors relative to the one below:

This is during the loading screen, any ideas why?

(CC22, Paid))

Copy and paste null.bmp from the main directory into devices.

To be more precise, go into base.rte and find something called "null.bmp", copy that and paste it into the base.rte/devices folder.

Null.bmp used to be in the Devices folder, and plenty of mods used it. Then Data moved it to base.rte one build, and lots of mods broke. The easiest method to fix this is the above mentioned.

Unfortunately this solution doesn't seem to be working either.

Only mods formatted for B22 are working at the moment

That might be your problem..

Yes, many mods "break" when a new build is released. I suggest disabling the ones that crash until their respective mod makers release a converted version.
