Manjaro Linux crashes after using Vital in Ardour

While running one instance of Vital.lv2 (free edition) using one OSC, and another instance of Geonkick with Dragonfly Reverb Bus, never had a problem with those. I was doing MIDI editing on 1024mb of buffer running JACK with Focusrite Scarlett 6i6 (1st gen).

Ardour 6.3

OS: Manjaro Linux x86_64
Host: MS-7817 3.0
Kernel: 5.4.78-1-MANJARO

This is the only info i could get on the terminal.
