Blank Screen on resuming mission

In essence, I can’t play Halo2 on TMCC as I have a life and have to save the game and stop playing, however if i save the game and quit and then come back to resume the mission later, it loads but I just get a blank screen, I can hear it running in the background and if I pause it I can see what is happening in the background. Blank screen after playing on legendary and getting past really tough bits, makes me want to smash up my xbox but mainly your game that I specifically brought the xbox one to play on. Only way to continue is to reset the mission and start again. grrrrrr. This isn’t fun, sort it out.
