Discord interfering with Moza stalks in ETS2

I received my Moza Multifunction Stalks this morning and have had issues all day trying to get them working in ETS2. They either didn’t work at all (in-game - worked perfect in Pithouse), or were extremely intermittent. After a while I noticed my CS Pro dash wasn’t working properly either, sometimes the rev light would flash up but mostly would revert to idle and wouldn’t show gear/speed. Realising it was an issue with the plugin, I started closing programs one by one, and discovered it was Discord causing the issue.

Anyone heard of this issue before?
