Huge Lag with Cubase 10.5

I’m having a huge lag issue with Cubase 10.5 compared to 10.

When I open up 10.5 and action I do there’s about a 2-3 second lag. So for example if I create a new track and start typing the name of the track, it waits 2-3 seconds before typing. and its pretty much the same with any other action of function. But when I jump back to Cubase 10, it works fine. no lag.

Anyone else having the issue and know what it could be? It’s driving me crazy. I’ve been using Cubase since v8, and have done every .5 update. And have never had a problem like this.

I am using an Apple iMac 3,2Ghz with 32GB RAM, a SSD system drive, and a Video GeForce 710 2GB Video Card. And I’m running Mac OS 10.14.5

I appreciate any advice. I might just end up downloading the installer again and trying a re-install.

Thanks in advance

maybe you need the hotfix for mac? v10.5.5

Thanks will try the Hotfix. I did delete the preference file and that id seem to help. But will also try the hotfix
