Cubase 9.5 Audio Not recording - FIX

I busted my gut trying to find a fix for the audio not recording or showing a waveform. I had a Line6 Spider V30 amp connected via USB, Cubase 9.5 would find it (ASIO), the sound would showup in the Mix Consoles. However, it wouldn’t record my freakn’ guitar input . I ended up by accident going to:
Project (Top Menu)…
Scroll down to - Project Setup…
Then change “Bit Resolution” to 24 Bit (Default is 16 Bit).
Whamo!.. Bang. it works (Turn off the small orange monitor toggle on the recording track to hear it back through your speaker setup!)?
I hope this has been helpful for anyone out there having this same problem. Phew!!!
