Re-enabling the OpenFX Plugin in DaVinci Resolve

When the OFX plugin causes a problem or crashes DaVinci Resolve it gets blacklisted and Resolve won't appempt to load it anymore. Even if you re-install a plugin or install a different version of the plugin.
In order to load the plugin again we need to tell Resolve to do so. Go to Preferences and Video Plugins section:
Re-enable OpenFX Plugins
Tick the checkbox next to the plugin, click Save and restart DaVinci Resolve. The plugin will be loaded on startup.
