Okay, so it is not possible for you to run plasmashell from tty.
Let's try attaching gdb to the already running process. Follow these steps
(some are copied from my previous message):

0. Add the kernel parameter 'sysrq_always_enabled=1' to the boot manager.
1. Run 'startplasmacompositor'
2. Switch to a tty, log in to your user and run 'sudo gdb -p $(pidof
plasmashell)'
3. In the gdb prompt, run 'set logging on', and then 'continue'.
4. Switch back to Plasma 5 with the proper Alt+F? key combination.
5. Reproduce the crash.
6. If the screen is frozen, press Alt+SysRq+R (unraw keyboard), and then switch
to the tty where gdb is running.
7. gdb should have noticed about the crash. Run 'bt'. Because of 'set logging
on', this has been saved to 'gdb.txt' in your home directory.
