Bug: Playout fails on default configuration

[milkywayfarer]

Observed Behavior

When I try to playout a png image using a clean install only with NDI added, this is what i get in the logs:

Last stack trace with no state error repeats every couple of milliseconds.

Expected behaviour

Expected it to playout correctly.

Steps to reproduce

1. Download CasparCG Server v2.4.3, CasparCG Client v2.3.0 from GitHub and latest NDI Runtime v6 from NDI.
2. Open server config, add NDI consumer.
3. Open media folder, add a random png file from the PC.
4. Start the scanner then the server, make sure that the screen consumer has opened and NDI is loaded correctly by searching for these strings in the logs: Loaded "C:\Program Files\NDI\NDI 6 Runtime\v6\Processing.NDI.Lib.x64.dll"; ndi_consumer[1|CasparCG_1] Initialized.
5. Start the client, it autoconnects to the localhost server and reads the library of one png file.
6. Add the file to the rundown, press F2.

Environment

• Commit: the one tagged with v2.4.3
• Server version: v2.4.3
• Operating system: Windows 10 latest

Perhaps running it with LOG LEVEL TRACE and report back.
