I’ve tested 3 projects and all threes previews have a black screen.

Yes, same. Started about 30 min ago - can’t preview anything - just keep loading.
Same issue for me. Was working great earlier today; tried reverting to older versions with no success.
I also tried the following:
- Cleared all browser cache
- Tried Edge InPrivate Browsing
- Tried Chrome Incognito window
- Tried creating a new, bare-bones project
Nothing worked - still no preview

Preview is blacked out on 2 of my projects. A third project has nothing but the chat box available.
Between Windows and an M4 Mac. On Each I;
Cleared Cache.
Tried Firefox, Edge, Chrome, in normal and incognito/private mode.
Safari on Mac.
Attempted to Fork the Third Project and clicking fork results in no action.
The two projects where preview is blacked out I actually received an error and asked v0 to fix it. So wasted some credits following up thinking I broke something:
The code returns the following error:
```
Failed to initialize LightningCSS: Failed to fetch
```
Revise the code to address the error.
I was previewing: /
Screenshot of the 3rd project with absolutely no options.
Glad I’m not the only one, but mad productivity is all but squashed for the day.
Wonder what’s broken…

Yeah dude I burned through more credits today too trying to figure out what was going on. I thought I bricked my entire project.

That’s weird, my project got the same exact error right before it blanked out…

I was able to fix my projects by restoring to a point before the preview disappeared.
I still got no preview, don’t know what to do and i had recently just paid for premium 
Thanks! So rolling back to a previous version did load the preview of the 1st 2 projects 
but it disappears again when I return to the latest version and I’m not willing to Restore it and walk away from all those credits and progress. One of those projects was not backed up to Github.
The 3rd project I provided a screenshot for, after inspecting element and troubleshooting, it seems the preview iframe isn’t rendering on any browser, on any OS, under any circumstance. So I scrolled back through the chat (since it was the only thing loading) and clicked on a previous version and voila. It forced the Preview iframe to load again. I was able to go “back to latest” and everything seems fine for this project.
It looks like this was contained within v0. (At the time of writing this the first 2 projects are loading fine now….yay.)
Thanks again

I’m facing a similar issue.
I found that by going to version 1 and clicking through each version one-by-one gets me back to where I left off.
Kinda seems it adds changes from each version one-by-one when I do this. If I skip a version as I iterate through, I don’t get the changes from that version and in some cases that would wreck the project as later versions depend on the changes from that version.
It seems version diff tracking is completely broken and it doesn’t matter if Github is linked or not.

Thanks for reporting everyone, we are investigating this internally
Hi i have the same issue. If i’m opening the chat the preview is not working for my last version and the LightningCSS error appears after some time.
I can confirm the workaround from @nielssoholm-3374 is working. For me at least it is enough to select first version, wait for the preview to show up and go back to the last version. The last version appears and all is working as expected.
