Davinci Resolve 17 Won't Start

Please help me, Davinci Resolve crashed on me in the middle of my edit. Now I'm unable to open the program. The loading window comes up like normal, saying "looking for control surfaces", but when it goes away the program doesn't open. I've been unable to open it before like this, various "fixes" have included running it as an administrator, restarting my pc, or waiting a day or two. However, this problem has never followed a crash before and none of my previous solutions have worked. I followed Scott Fichter's video, and none of his suggestions worked. He then said to come here. I've made and attached a log. Any help is very much appreciated. Thank you.

I had the same problem - see:

viewtopic.php?f=21&t=139117

A complete reinstallation - but only version 17.1 - helped me.

It would be interesting to find out what the cause of this instability is - I suspect it is related to the cache of the video files.

I've tried uninstalling and reinstalling twice when it first stopped working, and I've done it once again a day later. It still hasn't helped.

Can u list the nfo as well.

Turn off any cloud drive connections or apps to them.

Same thing happened to me on Version 16, and after nearly 3 weeks, I found that some software running in the background conflicted -- in my case a NAS cloud drive app. Once I got rid of that app, everything runs fine again. Others have stated their MS antivirus or MS Office cloud kept it from starting.

It is my belief that a recent Windows update broke something.

Before I fixed it, I was able to limp along and run Davinci in Windows 8 compatibility mode by right-clicking on the Davinci icon. Rendering speed was cut by over half.

It's been reported recently that deleting your preferences can help - in your case, whatever's in "C:\Users\Joe\AppData\Roaming\Blackmagic Design"
(Perhaps rename rather than delete just in case )
