FIX opens R terminal and Stalls

Hello, I was wondering if anyone encountered this issue before:
I just reinstalled FIX the ICA noise classifier. When I run it, the R terminal opens in the terminal and waits. If I close the R terminal with q(), FIX appears to continue on and then does the same thing. If I close R a second time, it appears to complete. I am just extracting features currently i.e. the first step. Im using Ubuntu 18.04 os and R 3.6.2.

Help would really be appreciated.
