Resolve Studio keeps failing to render .mov transitions

I am trying to export a project but I keep constantly being given this error message at random sometimes. Like there's 7 .mov extension based transitions with alpha channel. No, they're not inaccessible, they are on my drive and right clicking the media bin and clicking on "Open file location" takes me precisely there. Yet, Resolve keeps failing to do this.

My 10th attempt is above. Do I just have to re-encode all this into a different format and then make it .mp4 container? What's the deal here?

What's your hardware and GPU driver?

We also need the diagnostics logs, as per the FAQ

Guys, I found what's up with this, though not the why of it. My export attempt was in h265. The moment I chose H264, it worked flawlessly and exported just fine. My GPU driver is 580.76 Studio and running an intel i5 12600KF with RTX 4070 SUPER and 32 gigs of RAM. I think I am good for now, though there is still that question of why it wouldn't work with h265.

Because Windows OS Doesn't Have Support For H.265\HEVC Out Of The Box ?
