Proxmox AMD GPU Passthrough

I've been using a Proxmox home server for quite some time now without many problems. Recently i got an AMD Navi 10 RX 5700 XT and tried to pass it through to a windows VM. I mainly followed the official Proxmox guide but got it running by using some other tutorials too. For now, it works once after i reboot the host. Then its no problem to start the VM, but after a restart the VM doesnt start no more, showing this error: swtpm_setup: Not overwriting existing state file. kvm: ../hw/pci/pci.c:1637: pci_irq_handler: Assertion 0 <= irq_num && irq_num < PCI_NUM_PINS' failed. stopping swtpm instance (pid 98348) due to QEMU startup error TASK ERROR: start failed: QEMU exited with code -1` I tried fixing it using this but it didnt change much.
