No External FX in 10.5 update

Hi guys. I’m also having issues with the external fx. I use Zen Tour as my interface and I use its onboard fpga fx via external fx routing configuration in Cubase. It seems that those fx are not getting the signal and also, the signal doesn’t come from them, back into the Cubase. I have the exact same configuration as in C10, where everything works just fine. Any idea what might be the problem. I’m running MBP and Mojave.

Hello Guys … same pb here … the external FX goes outside , comes back in my RME totalmix but doesn’t show up in cubase !
It was working fine in cubase 10 … doesn’t work on 10.5 … plus enormous CPU overload issues !!
