It seems that a dependency libnss3.so is missing for the JCEF preview to initialize.

Possible directions to take here:

• reproduce the issue in a custom Linux VM
• when checking which kind of preview is available (JCEF or JavaFX), evaluate the condition that failed in the stack trace above earlier to allow a fallback to JavaFX is JCEF doesn't work
• offer an editor notification for users directing them to a page in the manual with a remedy (for example installing a missing package)
• for sentry reported errors, include the distro and version used, so reproducing the issue is simpler Report additional context information via Sentry #660
• raise this issue as a JetBrains issue as there is already an API JBCefApp.isSupported() that obviously failed here

Reported upstream. https://youtrack.jetbrains.com/issue/IDEA-267885

Closing this issue for now as there is nothing the plugin can do to prevent this error to be logged.
Will revisit it again once the upstream issue receives attention.
