I’m not sure if this is your answer, but I know video also requires Microsoft Edge Webview 2 Runtime. It should installed by default, but it might be worth checking Settings>Apps>Installed Apps to be sure it is present.
The troubleshooting steps you’ve taken are considered best-practices and to give credit where credit is due, Bambu’s wiki does a very thorough job.
However, there are two things that come to mind as possible solutions.
Trial and error approach
Brute force uninstall and reinstall of a previous version of Studio, not the current one.
Try installing Orca Slicer. Since it uses the same resource as BS, if it shows the same error then at least you’ve narrowed it down to a system issue not one related to the slicer. I know, not much of difference but it will affect your the trajectory of potential solutions.
Try to use a 3rd party uninstaller as opposed to the one in Win11. The generally accepted free utility(trialware) is Revo Uninstaller. I’ve used this with great success but it can be very, very aggressive so make sure that you create a system restore point before you use it. Revo will allow you to purge not only the files but all the registry entries. This will force any new installation to treat the installation process as if it were seeing the system for the first time.
Root Cause – Learn this technique and you will become the master of your own destiny.
Find out what the root cause is before delving thrashing through every solution you see mentioned on the net. While I realize this is much easier said than done, it will prevent you from going down needless ratholes.
Right-Click on start menu and review event viewer.
Your most interested in Critical And Error Messages. Note, depending on how old your system is, it may take many minutes for the logs to completely load and there is no status bar to inform you of progress.
When you find the error message that names a suspect program
Copy and paste the error into Google and add in quotes to the end of your search string: "Bambu Studio" -site:bambulab.com What this will do is reveal searches relevant to Bambu Studio while eliminating the the Bambu Wiki and this forum since presumably, you’ve already searched through these. Otherwise, leave off the “-site:” modifier to include them in the search.
Here is an example of an error for a custom filtered log I use when anything related to Orca or STLs causes issues. In this event I already know what happened, I tried to read a corrupt STEP file that my eViewer crashed. But sometimes, the program does not issue a crash message because it was a background program that crashed. That’s when Event viewer helps.
One tip I’ll share with how to use event viewer. Delete the event viewer logs before you start up the program you know will cause a system fault. Note the time of day that the program faulted because as you scan through all of the systems and application logs after you’ve deleted all the logs, you’ll see a lot of noise but you want to find the time stamp to note what the system logged as a fault.
Hmmm… at this point is when I start suspecting a hardware problem. Windows media player is a very ornery product when it sees a video feed it does not understand. There is no way to sugar coat it but Media Player is a utility Microsoft long ago abandoned when it comes to providing usable error messages.
One thing that could be a test to rule out hardware issues, have you tried viewing the camera through the Handy app? If you can’t view it through that, then that’s a smoking gun that the camera is either defective or perhaps the cable has come loose.
Also, have you tried on a different computer? That’s another option. Again, simply to rule out hardware as the issue not as a permanent fix.
It worked in Handy and on every other Windows machine I have (including this one before I reinstalled windows)
One thing I did different was when I did my fresh windows install, I went with a Release Candidate version of the next W11 update. Turns out something with that was an issue
Did another fresh windows install (4th of the weekend haha) but this time of the latest release version and Bambu Lab live view is working again.
Hope when that preview version goes public it doesn’t break Studio for everyone
Thanks for closing the loop and sharing your success. This will help others who come across the same issue. Also, kudos for not giving up. Many folks might have done so long ago. But let’s face it, when a machine starts acting up and you get so close to finding a solution, it starts to get personal and you just have to follow through…
I am having this exact same issue on my Mac (Sequoia MacOS 15.0). I’ve not been able to find anything about how to fix this on a Mac and nothing I’ve tried so far has worked. My video stream is still working on Handy iPhone and iPad.
"This is because you havn’t allowed Bambu Studio access to your local network.
After updating to MacOS 15.0 it probably asked you the first time launching Bambu Studio.
You can fix this by:
System Setting → Privacy & Security → Local Network"
