Seemingly random build failures without error messages

Hello, we're using Unity 2019.1.0b1 locally and builds work fine.
The Cloud build is set to use latest 2019.1 and it fails without providing any error messages.
It created a build and failed two in the same day. The only changes to the project that were made are some files deletions (mostly textures, models and sounds).
Clean build and normal builds from dashboard are getting cancelled.

As I said we're using Unity 2019.1.0b1.
Build target - Windows standalone 64bit
I'm using Windows 8.

 

It's hard to diagnose this without further details - if you submit a support ticket I can take a closer look at your project.

That said, we have been seeing a lot of timeouts during the asset upgrade process in the 2019 versions. If you download 2019.1.0f2 and run your project locally then you might see the same issue. If the upgrade succeeds then saving the results to your SCM would resolve these upgrade timeouts. That's just a guess though, it's entirely possible that you're experiencing a different timeout issue.

 

Thanks for your reply, I submitted the ticket.
