When using Art-Net to DMX passthrough, this stops after less than a minute.

Describe the bug When using Art-Net to DMX passthrough, this stops after less than a minute.

The only fix I've found is to have QLC+ also outputting Art-Net on the same interface in a different Art-Net universe (or even the same universe).

To Reproduce Steps to reproduce the behavior:

1. Select "Passthrough" for Universe 1
2. Select Art-Net for input on a network interface in Universe 1
3. Select DMX USB for output on Universe 1
4. ...nothing happens
5. Select Art-net for OUTPUT on the same network interface in any universe (including 1)
6. Works!
7. Unselect Art-Net output on the network adapter from step 5.
8. Continues to work for a bit...
9. ...and then stops.
10. Go back to step 5 and just deal with it. (I use universe 10 as nothing is listening to it)

Expected behavior It works right off and continues to work.

Screenshots

Desktop (please complete the following information):

• OS: Windows 11
• QLC+ Version 4.12.6 and also tested 4.12.7.351
• hardware setup: Generic FT232R DMX USB, and WLED generating Art-Net output code.

Additional context I wrote the Art-Net "virtual LED" output in WLED and it seems to pass all checks with Art-Net software (and QLC+) and also Wireshark'ing it shows no issues and the packet decoding.

QLC+ does this passthrough flawlessly as long as it's also outputting Art-Net in some universe on the same adapter.
