To be very honest, I have no idea, but disabling OODLE it should be temporary solution only.
I guess the only way to find out is to make a build of your game and test it.
It has also spread thorough other my projects what makes me feel, something broke in the engine because I didn’t have such a problem before as well as I didn’t have it in any other versions of Unreal Engine editor beginning from version 5.0 until 5.5 and even 5.5 was fine when I just moved to it, but all of a sudden materials begun to switch black and glow for no reason.
I used “Verify” on editor through launcher to check integrity of editors files - showed nothing, changed nothing
Next step I going to do is reinstallation of the editor and see will it fix the problem, I will get back when I do.
