For info:
In my particular case, it was not due to tagged and untagged mix. The problem persisted, even though I only use tagged interfaces. During the update something was changed in wiregard, without wiregard everything works. If I switch back to tagged and untagged, everything also works, just without Wiregard.
I suspect that Wirecard handles the route differently than before.
