Raspberry pi 4 problems

I get greeted with either of these two screens when i try to boot up my machinee. its a fresh install of linuxcnc 2.93 on a raspberry pi 4 cm4 and a 7i96s, i have tried with other realeses but the issue remains the same. if it loads in to the program thee error messages pops up after a few seconds so not instant. Does anyone maybe know why or could point me in a direction because now im completly lost

Is it  possible you have lost the link? (maybe 7I96S 5V power issue)

What does:

sudo chrt 99 ping -i .001 -q -c 10000 10.10.10.10

report?

(will run 10 seconds and report ping statistics)
