As long as you are in the diagnostic mode, you can just diconnect the cable. Shutdown the job 1st, then exit the program.
The 1st 2 thing I would address would be the battery unvoltage, & the BSD line from the alternator. Take a screenshot of your codes, then delete them. If the codes come back, then address them. How old is your battery, & do you ever charge it? Since our cars drain so much voltage from the battery, it should be charged monthly, with some type of AGM battery charger. Once the battery is charged, the other problems might go away?
If you have a VOM around the house, measure the battery voltage cold, with the engine off & the headlights on. The battery should be above 12 volts. With the engine running, the voltage at the jump terminal should be around 14 volts.
