I believe that's the thing mate. It's very old by now, that's why everyone at this point should be using the developer build of the engine. Download one of the recent CE v.1.11 ALPHA builds (I'm running ALPHA 54 rn) from github. Had no problems with them whatsoever, all stable so far.
Mikulu did the video on where and how to download the dev build
That should do the trick hopefully
