Tests that happend to get 20240310.1.0 image are all crashing on startup:

Is it regression?

Yes. 20240304.1.0 works just fine. For example another job from the same run: https://github.com/ovsrobot/ovs/actions/runs/8237626849/job/22527053666

Expected behavior

All the built binaries should not just crash.

Actual behavior

All the built binaries are crashing on start.
