Projectgenerator (CL or GUI) hangs for only one of my projects

despite attempting to build with or without addons, one of my projects seems to hang after listing all files in command line (project gen works correctly when updating other projects)

I am at a loss (have reinstalled OF, have removed one addon at a time) and was curious if anyone ever ran into this and what I should try next.

I also wanted to note this bug I found while building command line project gen:

"$(OF_PATH)/libs/rtAudio/lib/osx/rtAudio.a"
should be:
"$(OF_PATH)/libs/rtAudio/lib/osx/rtaudio.a"
