iMac pro 15 sec sound latency when cubase dongle connected

Hi, I have decided to go back to music, took out my cubase dongle, downloaded the software, but here is an extremely annoying thing: each time I connect the dongle to the imac and run cubase, my computer starts experiencing a ~15 sec latency in sound when outside of cubase.
I have tried to set it to “release the audio driver when in background” but that solves nothing.
And I tried to contact the local distributor, who is supposed to be the support for us here, but he doesn’t come back to my mails (and a month already passed with this problem).
Would be glad for any help, thx

See the “german” in the forum header…!?
And even in the english forums some useful info might be necessary.
