Rush won’t render project

Of course I have to ask the obligatory "Did you run an update? Did you sign out of Adobe and back in again?" questions, because in the majority of cases, these are the fix. 
If you're still experiencing the same issue, do a quick test: try exporting out the Sample project that came with the app. If it exports fully, you may be looking at 2 causes for your own project not rendering: 

Something is corrupt/not working properly with a Graphic/Title/Overlay in your project - try removing or replacing with another version to see if it makes a difference.
Something is corrupt/not working properly with your source video, audio, or graphic content - Make sure your source content is .mp4, .mov, or other supported video format; if not, you might need to "preflight" your video using Adobe Media Encoder or Handbrake.fr (easy to use). 

Let us know if this does the trick!

I've been trying to render my video for one entire day. You're telling me I have to remove all titles and all fonts???? This is ridiculous. I can't believe this issue keeps coming up, everytime I use rush mobile. It's a disgrace.

I had this same issue with rendering on my iPad pro. I didn't have any titles to deal with but i was using a pan &zoom feature, once i removed that and locked the media it finally rendered!

There's always something with this app... For me I'm now getting this issue... it's rendering till 17% then stopping and closing the app. Bloody rubbish and waste of money that I spend on my subscription 

Ok.  What a goat-rope, especially for a professional product.  I was having similar problems with Premiere pro, rendering H264 video.  It locked up every time.  So, I found a fix for pro by unchecking the hardware acceleration under the preferences menu.  The same thing worked for rush, although the menus and commands were slightly different.  Seems my graphics card was not recognized by the program.

I also have this error and im on ipad 6 and i've tried to lock the layers but it just doesnt work.

I noticed that if I try to make a video using footage from my GoPro, i receive this error message.

If its video footage from my phone, it works successfully. 

I figured out a work around!

I LOCKED All the video and audio tracks and then it rendered. I think the issue is the graphics/text, but if I lock all the tracks it worked.

Mine won't render and it's 2020. What a waste of time. This has happened to me time and time again. I don't even know why I use this program. It's disappointing.

I am having this issue now in 2020. I thought maybe I just needed to wait for an update to come out, so I did and I am still having the same problem. I have never had this problem before. It is just stuck on rendering with 44 seconds to go and will not move. My system is up to date and meets all required specs, I let is sit for a long time hoping time would fix it and nothing. Then I go to cancel and reopen rush and it will not open. Please fix.
