The TCAS is real, you are required to follow the RA.

Forgive me for asking, but if I can't raise tower and TCAS is going
off, and the CDI shows I still have not intercepted the localizer, my
first priority would be to fly the airplane on the last assigned
heading and figure out if the TCAS warning is real. Attempting to go
back to the last assigned frequency will be a low priority item, no?
