Can't switch tty's or tmux windows on Linux?

I'm running Debian Trixie (without a desktop GUI) on a raspberry pi zero 2w. Currently using pico8_dyn from the raspberry version of PICO-8 (I think the normal version needs a desktop?). 

I am trying to get it to where I can switch to another tty or tmux window while I am running PICO-8 so I can tail my log file where I printh() to. 

However it seems like PICO-8 intercepts all keyboard shortcuts. So I can't ctrl-alt-F2 or ctrl-b + 1 while running PICO-8. I tried it with windowed mode set to 0 and 1. Also tried reconfiguring tmux shortcuts. Any ideas on how I can get this to work?
