whonix-workstation randomly close on debian/KVM


I’m new to whonix, just installed it with KVM, on top of a full disk encrypted fresh debian 12.

whonix-workstation randomly close/crash, seemingly out of the blue. It’ not very often, and only happen after a few hours of work in the vm.

i’ve slightly tweaked the vm, but probably nothing to explain that issue : i bumped memory to 12g and CPU to 4.

Others vm on the same KVM/qemu do not have the same issue, afaik. Neither whonix-gateway, nor the debian and arch based VM i also use experience it

I’ve no idea where’s the issue coming from, any help is welcomed
