Just a few questions, what OS are you using to program? Mac, Windows,
ChromeOS, Web App? Have you made backup copies of your code and then
reinstalled the App? Did your team copy and paste code blocks on the app
page, when we used blocks coding that used to be an issue. Upload one
program at a time, starting with one that is known good, does it work? Keep
going until you run into the one that doesn't. If one causes issues, then I
would suggest starting on a fresh program writing the same code to see if
there is an issue. If the first program doesn't work, then disconnect all
ports and test each one with a motor and sensor that is new or known good.
As a final resort you can try the following:
When you do a firmware update it clears all of the memory. You can try to
downgrade the firmware to V2 and then do an upgrade back to V3. I've done
that in the past to "resolve" some really weird issues. Just follow the
instructions to do the downgrade then open the Spike V3 app and perform the
upgrade to V3 firmware.

You can also try PyBricks custom firmware then going back to Spike but
unless you have a PC/Mac and some background into drivers as well as
putting devices into DFU mode I would refrain from doing so.
Let me know if any of this works out for you all.
Thanks,
