Running Cura on my computer would work fine, until a few hours later my graphics card would freeze up and wouldn't register anything.
After a reboot everything would be fine until the next time I launched Cura, it was like a time bomb.
All this has been happening with Ultimaker_Cura-4.6.2-amd64.exe on Windows 10.

A variety of other people are having similar problems and one suggested solution was to run Cura in a VM.
The final comment on the thread suggests turning off the Containerization feature in Windows 10. THAT WORKS!
If you need containerization for docker and don't want to get rid of that feature, consider running Cura in a VM like VirtualBox.
After a lot of trial and error with VirtualBox versions, VirtualBox 6.0.6 is works with the latest Linux Mint.
Some other prerequisites of using VirtualBox include checking what optional features of windows are running:

Here is a link were I talk about the VirtualBox 6.0.6 version:

So after you have a version of VirtualBox installed grab a copy of Linux Mint or get a premade VDI.
I went the premade VDI route.
On this page click the tab for VirtualBox and select one of the versions. Xfce is less graphics heavy, so may be a good candidate for virtualization.

https://sourceforge.net/projects/osboxes/files/v/vb/31-Lx-M-t/19.2/Xfce/19_2X-64bit.7z/download
Using 7zip, extract the image for Linux Mint from osboxes.org to somewhere easy to find.
In virtual select New.
I gave mine: Call it mint, with 4096 MB of RAM and select an existing harddisk.
Find the VDI file you extracted with 7zip.
Open it up and let it boot up. It will be windowed pretty small so you need to install Guest Additions to get it to go full screen.
Follow these instructions and Guest Additions will be ready to go quickly:
https://linuxize.com/post/how-to-install-virtualbox-guest-additions-in-ubuntu/
Basically attach the Guest Additions from the VirtualBox menus, then open a terminal in Mint and put in these commands:
sudo apt update; sudo apt install build-essential dkms linux-headers-$(uname -r)
sudo mkdir -p /mnt/cdrom
sudo mount /dev/cdrom /mnt/cdrom
cd /mnt/cdrom
sudo sh ./VBoxLinuxAdditions.run --nox11
Now you have Linux in Windows and full screen!
The version of cura in the default repositories is Cura 3.1 . You can use that one, but it doesn't
include most of the newer printer configurations.
To get the latest one go here and download the link for Linux:
Go thru Git Hub if you are browsing on Windows...
https://github.com/Ultimaker/Cura/tags
https://github.com/Ultimaker/Cura/releases/download/4.6.2/Ultimaker_Cura-4.6.2.AppImage
Or on Firefox in Linux, open the main downloads page on the Ultimaker's Software portal
https://ultimaker.com/software/ultimaker-cura
https://software.ultimaker.com/cura/Ultimaker_Cura-4.6.2.AppImage
After you have downloaded the .AppImage file, you need to run it. You can made it executable with
an option in the Properies right click menu (a checkbox near the bottom) or from the commandline put this in:
chmod u+x ~/Downloads/Ultimaker_Cura-4.6.2.AppImage
Double click it the .AppImage file and you now have Cura 4.x running in Linux with protection!
sudo mv ~/Downloads/Ultimaker_Cura-4.6.2.AppImage /opt/
sudo chmod a+x /opt/Ultimaker_Cura-4.6.2.AppImage
ln -s /opt/Ultimaker_Cura-4.6.2.AppImage /usr/bin/cura
