Pro Tools 2018.3 HD Driver crashing

[sowattmusic]

Hi

I normally works in Logic Pro X for programming and then in Pro Tools GD for mixing.

Up until now working in Logic Pro with Avid HD Driver as the audio interface was flawless, Since I updated to 2018.3, and therfor to the new HD driver it now crashes.

Logic Pro stops playing audio and I get the message:
" You can't open the application "AvidAUdioServerLauncher.app" because it is not responding".

Work Around as of now: if I "Force Quit" the audio server (By killing the process in The activity Monitor) and relaunch Logic Audio it works.
But it does crash again after about 3 hours of working inside Logic....

Any help?
Thanks
