Under DaVinci Resolve 19.0, not only does the DaVinci Resolve Control Panels app crash immediately when I try to start it, but Resolve itself also refuses to start as long as the app is installed. In both cases, the Windows Event Viewer displays exception code 0xc0000409:
Fortunately, uninstalling just the Control Panels app allowed me to work with Resolve again. However, whenever there’s an update available for my Speed Editor, I need to find a workaround. Previously, I installed the Control Panels app on a different computer, but this time it was even more frustrating, as it also crashed on that second machine.
What eventually worked for me was temporarily disabling all other startup applications. A simple way to do this is by pressing the Windows key + R, typing “msconfig,” and then selecting “Selective startup,” leaving only system services checked (unchecking “Load startup items”):
After restarting with this selection, DaVinci Resolve Panels ran just fine and updated my Speed Editor:
Once done, I set the selection back to “Normal startup”. I did not have the patience and time to go through the startup apps and disable them one by one to find which one was causing the conflict. You could do this in the “Startup” section of the Windows Task Manager or with other applications like Autoruns.
