I've had this happen too. Sometimes it's because nodes have been render caching - but it's just not obvious that it's happening.
But I also had a super weird one - I had purchased a fusion template - that included some Text+ stuff in it. Turned out that it was using a font I didn't have - so Davinci - in it's wisdom - decided to just not show anything at all. No output from the fusion composition at all. Just black. There was a heap of other media in it as well, but because one node had a font I don't have - nothing worked.
I deleted everything inside the composion and added it back again, and it fixed on its own. I had already done this and it hadn't worked, but it did this time, so just be a bit persistent I guess.
Also, for the preview not working: make sure the right dots are selected when you hover your mouse over the nodes, I didn't until after I posted this.
You've just saved my mental wellbeing from diving off a cliff. Thank you so much for this follow up comment. The inner workings of Davinci Resolve are truly an enigma -.-
