Linux VST3 + Ardour 6.5 100% CPU spike

When removing or deleting Vital VST3 from a MIDI track in Ardour 6.5 one of the CPU’s on the system I am using will max out to 100%. This 100% peak will move from core to core

Operating System: Debian GNU/Linux 10
KDE Plasma Version: 5.14.5
Qt Version: 5.11.3
KDE Frameworks Version: 5.54.0
Kernel Version: 5.9.1-rt20avl1
OS Type: 64-bit
Processors: 4 × Intel® Core™ i5-3470 CPU @ 3.20GHz
Memory: 11.4 GiB of RAM

this peaking of any of the CPU’s does not occur when unloading the VST2 or the LV2

Ardour has to be shut down for this behaviour to stop.
