Sky Q Box keep freezing and picture turns pink on screen afterwards

My Sky Q box keeps locking up after a short while from power reset.

I have tried a software firmware update by holding the front standby button on boot up but this has not fixed the issue.

Sorry meant to add after lock up it freezes on a pick screen and I have reset my TV too

Getting the same problem over the last few days. Was there a fix for it, or was it a new box?

No fixes - Seemed to start when we swapped to EE!  Still not working after 3 box swaps.  Running on WIFI which isn't great
