Big sur delay compensation

I just upgraded from Mojave to big sur in order to use cubase 12. I now have a big problem with my external fx and latency. When I try to calculate the latency, external effects max out the slider at 100 Ms. I have tried to calculate the latency using Gainmatch and get a staggering 14328 samples. I never had this problem before. I use a Motu 1248 interface BTW

The delay depends on buffer size and ASIO guard settings.
