Raspberry pi 5 freze

Hi and so much thanks to the people made all the work with the linuxcnc for raspberry pi 5 ,its a great job.
I have downloaded 4.8.9 and it's a great distro working so fine from beguining and today after a week or two the program stop and freze after 5-10 min. I can still run the stepper from the keyboard and the speedometer on the spindle is i ok and run but the rest of the program stop . the only way to go on is a hard rebot and then it start fine and then the problem starts again . Are there people who can help me in the right direction 
I use the byte2bot board in Lathe config. /krister

Hi I have difficults to use terminal its a little bit over my competens in linux ,but I change the cordless mouse to a mouse with a cord and after this the program are esier to work with the most off lagging diasapeard and I also changesd the Base period to 150000 and the Servo_period to 1200000 , after that i open up the idex setup file and set it to setp lowpass.0.gain 0.01 .

Its work great two weeks until today when the program freez again , after hard reboot it starts again .
One strange thing is during running a program nothing happens but if I take a coffebreak and the program idle the famos latensy varning came up on the screen . yors sinserly Krister
