Grasshopper software ( Rhino 7 ) is freezing and crashes

Problems could also come from some plugins you use in Grasshopper. You could try to find which component leads to a crash.
If you can post the script ?

There are a few things you can do now Johnathan.

Update the video driver.
Update Rhino (preferably not cracked)
Remove 3rd party plugins (enscape)
Verify your Video card is correctly configured.

Post the script giving you issues.
