I see you made two threads, hope you get the info you need. Maybe a Mod can delete the other one.
1) why did you replace the battery? Was there any fault or issue before you did that?
2) Is this a brand new battery? Did you do anything to reset the BMS
3) Sometimes the electrical weirdness is from a low charge. Have you checked the voltage and/or put a charger/maintainer on it?
4) Can you let it sit overnight (or 8 hours) without interruption?

My brake light sensor had gone bad, not realizing that I went ahead a replaced it with a new Optima yellow top battery, after that i replaced the brake light sensor and reset the BMS and also let the truck sit for a month without turning it on and nothing, the light comes on after about 10 minutes of driving and after that the cruise control will no longer engage.

Freddy, why are you going about this that way?
Get a code from the cause and begin from that known point, to diagnose the issue.
Otherwise, you are wasting your effort.
Leaving a vehicle set for a month drains the battery down.
Many systems on the vehicle are still alive with the ignition off and gas can start to get stale.
Then you can get into multiple issues just from setting.
Good luck.
