@GregValiant, thanks for the suggestion, unfortunately that did not work. However, after doing some more digging in my display settings I discovered that I was using the monitor connected via the USB Dock (DisplayLink) as my "main display", and it appears the Cura attempts to place itself on the "main display". I changed the setting so that the main display was connected directly to the laptop instead of the dock, and Cura started successfully. After some more digging, I found/remembered that a few months ago in Settings > System > Display > Graphics settings I set Cura to always use my Nvidia graphics card (on a windows laptop with dual graphics). After removing this setting everything started working again regardless of what monitor was configured as the main display. Obviously, Nvidia cannot render the graphics over a USB adapter, and it seems that setting was causing the issues with the Cura rendering engine.

Sorry - I was not able to edit the previous post, I assume due to needing moderator approval. I believe I found the source of the issue. I often go days without restarting my computer (or Cura). I recently added a Dell USB 3.0 Docking Station (D3100) to be able to add an additional monitor. When this 2nd monitor is attached, Cura 4.9.x crashes, but works fine if I simply unplug monitor's HDMI cable from the back of the dock. I've attached stderr.log files for when the displaylink monitor is in use and when it is not. My (hopefully) temporary solution is to unplug the monitor, launch Cura, then plug the monitor back in. Cura seems to run fine with the 2nd monitor attached but will not start without crashing. stderr.with.displaylink.monitor.log stderr.without.displaylink.monitor.log

I'm having similar issues after clicking on the "Monitor" button. I've tried completely removing Cura and all settings, but the issue persists after the following steps: Uninstall Cura 4.9.1 (including removing settings) Delete %appdata%\cura* folders Reboot Install Cura 4.9.0 or 4.9.1 - crashes still occur. If I install cura 4.8.0 the software restarts as if it's the first time it was installed. However on v4.9.x it seems to be loading the settings from the session where it initially crashed (after clicking the "monitor" buttom/tab). Is there a way to completely remove all settings to restart at factory defaults so that I can restore a backup of my settings from prior to the crash?

Given that you can't override the profile/sidebar settings, is there any way to identify those items in the material profile settings tab and identify/mark them somehow? I would really like to have the material profiles set the temperature/bed/flow rates rather than have them stuck/controlled by the profile.
