Spectaculator has stopped working. I'm using Bitdefender Antivirus

As of September 2026, Bitdefender has compatibility issues with Spectaculator. Symptoms include:

• Spectaculator initially runs fine after installation. On subsequent runs, it crashes after the splash screen, while showing Searching for plugins…
• Spectaculator simply crashes at startup.

Until Bitdefender fix the issue, you can work around it by adding an exception for Spectaculator:

• In Bitdefender, go to Advanced Threat Defense → Exceptions.
• Add C:\Program Files (x86)\Spectaculator\Spectaculator.exe.

After doing this, Spectaculator should start normally and continue to work correctly.
