At what point do I worry

Was supposed to have an IC internship last summer but couldn’t be onboarded because of the hiring freeze. I ended up working somewhere else where they could check my clearance and they said that it had been granted. HR asked for updated transcripts, resume, etc some months ago. I know that others in different career fields have already gotten their FJOs. HR hasn’t responded to my emails for 1.5 months. The internship is supposed to start in mid june. Should I be worried? Would they tell me if I didn’t have a job?
