As the title suggests osmc crashes everytime I have it on 4k60 resolution. For example once I turn on osmc, after 30s of proper use , it turns off turning the screen black and giving no signal on TV source. This happen always and I have tried rebooting it, updating ,upgrading . I used to play 4k60 videos on libreelec the beginning of the year just fine and when I switched to osmc I have the specific problem which is very frustrating. The osmc is up to date ,power supply 3.0A(5.1V).
I would really appreciate any kind of help, thanks 
P.S the TV fully supports 2160p/60hz and this issue exists only on 4k30/4k60 and not on lower resolutions. I must also note on 4k30 the interface is very laggy and it crashes but not everytime I open it like the 4k60 . And to make people understand around how much time after the boot it crashes for 4k60, it crashes around the time that it is scanning the library while when it scans the library on 1080p120 it works fine. The TV is Philips Ambilight and my device is raspberry pi 4b 8gb ram model for reference
