ArriRaw MXF causing Resolve to crash

Got a weird issue.

Running Mac OS 11.5.2 on Resolve 18.0.4 Build 5.

Anytime I try and play a ArriRaw clip in Resolve it crashes. Doesn't matter if it's imported, or just previewing it in the media tab.

Arri Reference Tool can play the clip fine.

The clips play fine on an iMac running Mac OS 11.3 on Resolve 18.0.4 Build 5.

Mac in question is a Mac Pro 2019, 2.5 GHz 28-Core Intel Xeon W with 512 GB 2933 MHz DDR4 memory and a AMD Radeon Pro Vega II Duo 32 GB graphics card.

Any thoughts?

had the same issue - had to update to Monterey which fixed it.
When on big Sur it would only work when using 1 GPU

Upgrading to Monterey is the solution.

If you can't do that, a (poor) workaround is to manually configure Resolve to use a single GPU.
