Qemu unexpected closed after motherboard exchange

Hello all,

I have the following problem:

two days ago my motherboard (MSI Tomahawk) died and I replaced it with a MSI Tomahawk MAX. After the installation I enabled my virtualization and iommu in the BIOS. Now I want to start my Windows 10VM again, but I get the following error message:

Error when starting the domain: Internal error:
