One tail light does not work, but brake light does

[epicdadbod]

So the other night I go to get into my 2020 Ram 1500 crew cab and I notice a taillight was out when I unlocked it. So I thought no big deal I'll change the bulb the next day, although I felt it was rare since a 2020 and only 39k miles. So I get the bulb changed, turn on the truck and it works......but now the other side went out. Then I looked at the bulb I had just replaced and it looked completely fine. I realized the brake light still works and the turn signal, its just the running light. Since it just switched sides after replacing the other I am assuming something with wiring. Any ideas? Of course it is out of warranty so now its my problem.

Switch bulbs side to side and see if the problem follows.
