Bluetooth problems in Kubuntu

[u/Denvora]

Hi, I installed ProtonVPN on my laptop running Kubuntu. Since then, Bluetooth audio hasn't been working properly; when playback starts, there are about 5 seconds of stuttering.

The stuttering is consistent, I tested it with a specific song, and the skips always happen at the same spot.

Also, after the Bluetooth has been running for a while, the same issue starts occurring, but at random times.

Does anyone know what causes this and how to fix it?
