keeps crashing

Hi All, my draftsight keeps crashing every 20-30-40 minutes i am using it. suddently my drawing starts to appear/disappear when zoom-in/zoom-out and after that it crashes. My laptop is less than a year old (intel i7 + nvidia geforce rtx 3080) and i cannot understand why it crashes (sometimes i need to turn off the computer and restart). do you have any idea why this keeps happening?
