KNX integration preventing ETS tunneling

Hi,
I noticed that the KNX integration recently causes an IP tunneling problem in ETS (5.7.7).
ETS states the following error: “The interface cannot be opened, because the connection type is not supported. Please contact the manufacturer of your interface.” My KNX gateway is an EIBPort v3 (last firmware 3.9.3).
At first, I thought the problem was elsewhere but had no valid culprit.
I then tried to completely shutdown my Home Assistant server and the tunneling worked again in ETS.
For info, it was previously working fine but not anymore in Home Assistant Core 2022.5.5 and Home Assistant OS 8.1 (RPi4).
Thanks for having a look.

Which version were you running before?
How many concurrent tunneling connections are supported by the interface?
Are there any logs?
Where / when exactly does ETS show that error message?
Are you reloading the Knx Integration sometimes from UI?

Thanks for your reply.
I think I found the real source of the bug inside of Home Assistant. It was a node-red KNX node I completely forgot about and that probably was still using the tunelling causing the bug in ETS.
