Jonathan Blow expressed frustration on social media about delays in opening MP3 files in VLC Media Player, which he claimed could take over 30 seconds. A community note suggested that Microsoft Defender might be contributing to the delay. VideoLAN, the organization behind VLC, responded to the discussion, while Blow maintained that VLC should address the issue, despite acknowledging a faulty AMD graphics driver as a factor. Users on Reddit indicated that adding VLC's folder as an exception in Microsoft Defender resolved the delay. Steps to create this exception include navigating to Windows Security, selecting Virus & threat protection, managing settings, and adding an exclusion for the VLC folder. After creating the exclusion, the time to open an MP3 file decreased from approximately five seconds to under one second.
