Render failed w/no explanation?

I am trying to export a video but every time I try it just says "failed" after a couple of seconds on the rendering progress window (with no further info).
I have just updated to DaVinci Resolve 16.2.8 to see if that would help but no change. I'm not that advanced with this stuff so any help is appreciated.

We'd need a lot more info to try to offer some guesses. Which hardware (CPU, GPU, RAM, disk I/O speed)? What specific version of Resolve? What OS? What source material? What timeline resolution? What framerate? How does your drive rate with Blackmagic Speed Test? Which GPU drivers are installed? What format are you trying to render to?

Usually when I have a render fail, it's something really stupid like "we ran out of disk space." It would be nice if Resolve could do the math, check the available drive space, and then warn in advance, "there may be insufficient space available." But I get that this is not always possible, since there are a lot of variables in any file export.

Worst case, try dropping the render speed and see if that has an effect.

Go to Preferences>User>UI Settings and uncheck Stop renders when a frame or clips cannot be processed.

Report back.
