ASIO problem with DaVinci and the DeckLink 8K Pro

Hello,
I have the following problem with DaVinci and the DeckLink 8K Pro video card:
As soon as I switch DaVinci Resolve Studio 18.6 to ASIO under Preferences and then close the software to update, DaVinci Resolve crashes when I restart it and can no longer be opened.
After a lot of troubleshooting, I noticed the following behavior:
If I deactivate the Blackmagic DeckLink 8K Pro video card in Device Manager, I can work with all ASIO drivers in DaVinci without any problems.
Is this a known problem or is it due to my card?

Is the host still crashing with Desktop Video configured as the IO Engine with the Decklink?

A link to diagnostic logs may be useful. Instructions in the FAQ: viewtopic.php?f=21&t=90190#16

Hi, thank you very much for your reply!
I created a zip file of the crash.
Can I send you the zip file or what information should I publish here?
How to configure Desktop Video with the Decklink as an IO Engine?

Thank you!

You're in good hands with Reynaud, but I would just ask, since it's not clear from what you're saying, are you trying to use 'Blackmagic Audio' as your ASIO driver? Or what is your audio device/card, since you didn't say? The BMD ASIO driver is legacy and has never worked, because of hardware limitations, across all BMD i/o devices; and will produce crashes.

Hi Reynaud, here is the link to the zip file:

Hi Steve, I use Ferrofish A32 Dante.
When I switch the I/O engine to ASIO in DaVinci under Preferences Audio I/O I get the following request: Changes will take effects the next time Resolve is started.
After this change, a restart is no longer possible and DaVinci crashes.

As soon as I deactivate the DeckLink 8K Pro in the device manager, DaVinci starts with the ASIO settings of my external Ferrofish A32 Dante sound cards.

Can you please include a screenshot of the current configuration:
Resolve Preferences > System > Video and Audio IO

In the attachment I have uploaded the desired screenshot of the current configuration.

Are the crashes reproducible with both the Delta 1010 and Ferrofish A32 ASIO drivers?

Hello, the sound card doesn't matter, as soon as I switch to ASIO DaVinci can no longer be started. I deactivated the sound cards individually in the device manager, and that has no effect either. I can only work with ASIO if I deactivate the Blackmagic DeckLink 8K Pro graphics card.
