This issue firstly occured on PvP EU, when I suddenly got kicked for the reason that my Battleye client wasn't responding. Upon trying to rejoin, I couldn't interact with anything, and as soon as I opened my inventory it instantly went down. Worth noting is also that it was acting like I wasn't in my company at all, and I couldn't see any of my ships names etc. Now this error has now also started to appear on PvE EU aswell, so it doesn't seem to be server related. I've also done some research which shows people has had this issue all the way back since the beginning of 2019. With no actual fix that works to a 100%.
