Constant Crashing in Color Picker - Harmony 12 Premium

I have a Windows 10 PC that was recently reformatted and reset with a clean install of Harmony 12 Premium.

Almost immediately, Harmony 12 began showing signs of constant crashing while playing around the Color Picker view.

This usually happens when I am trying to pick a color in the graph (click on it) and/or selecting gradient or solid types of colors.

The crashes persisted in:

-Newly made Scenes.
-Opened older scenes.
-When Harmony is the first and sometimes only major resource intensive program running after a restart.
-Windows 10 is fully updated.

This type of problem has only been prevalent after my upgrade from Windows 8.1 to Windows 10, and again… with a formatting of my C drive and a clean install of Harmony 12 Premium 12.2.0 (10711).

The crashes are so consistent, that the program is becoming unreliable, and I may need to switch to (sigh) Flash in order to continue on with my current projects.

Anybody knows what may be going wrong, or what type of things I can do to assist in solving it?

Consider updating your graphic card driver or contact support to
make sure that your graphic card’s settings are not set to use features
that are not supported by the card. Graphic card driver settings can
sometimes change from their defaults following a Windows update.
In your case it’s odd that a newly installed graphic driver would use
bad settings but if it does, try installing a different version of the driver.

You may be able to get more info from the Windows Event Viewer:
Application Event Log details for the Harmony crash.

Just to report back on this issue:

I updated my nVidia card, thought it may have made a difference, however, Harmony seems to still crash with the color picker.

The crashes SEEM to be less consistent. I have actually been able to function within the program this time, although, I’m not sure if this is basically some luck of the draw, or if I will revert to frequently having crashes every few minutes with the program like I did previously.

But the crashes still occur, just less frequently.

Can you swap out your nvidia card entirely and use another gpu or onboard to test? Since toonboom uses the 3d gpu for the opengl render its possible its crashing due to your gpu failing, but it’s hard to say unless you swap it out to test.
