I am running a Pi400 4GB. I've got the device connected to a monitor. I previously tried ubuntu20.04 and this loaded okay.
When trying Ubuntu MATE 20.04 64bit the Pi very quickly turns off. I've turned the Pi on without the SD card in and the general Pi screen loads stating the SD card isn't inserted. Once I insert the page turns to a colour wheel style page before going blank and the green light on the Pi400 disappears.
Does anybody have any idea why this is happening?
Ubuntu MATE version:
Pi 400 version:
(I've read similar questions regarding HDMI display but this doesn't seem to be the issue as the Pi itself turns off.)

I would recommend you to check power supply voltage if you are not using official power supply by Raspberry Pi foundation and if you aren't experiencing the same issue with other operating systems like Raspberry Pi OS then format your SD card flash Ubuntu Mate properly. Using Raspberry Pi imager is one of the easiest ways. I hope that solves your issue. : )
