Build errors in Canvas

Unity Engine
1

I had to copy the AndroidPlayer playbackengine folder from a new version on another machine than the 2019.4.29f1 version I’m using as Unity Hub refuses to install the Android components (I’m uninstalled and reinstalled 5 times :frowning: ) and now when attempting to build the Android version I’m getting weird errors:

Library\PackageCache\com.unity.ugui@1.0.0\Runtime\UI\Core\Layout\CanvasScaler.cs(241,20): error CS0117: ‘Canvas’ does not contain a definition for ‘preWillRenderCanvases’
Library\PackageCache\com.unity.ugui@1.0.0\Runtime\UI\Core\Layout\CanvasScaler.cs(253,20): error CS0117: ‘Canvas’ does not contain a definition for ‘preWillRenderCanvases’
Library\PackageCache\com.unity.ugui@1.0.0\Runtime\UI\Core\Layout\CanvasScaler.cs(302,43): error CS1061: ‘Canvas’ does not contain a definition for ‘renderingDisplaySize’ and no accessible extension method ‘renderingDisplaySize’ accepting a first argument of type ‘Canvas’ could be found (are you missing a using directive or an assembly reference?)

Any ideas why I’m getting this? Seems unrelated to a platform. The Windows version builds just fine.

You cannot copy playbackengine from a different Unity version, the errors you’re seeing might be the side effect of this.

Not sure what’s the issue with hub, but try manually deleting Unity installation folder and then attempt the install. In case of file lockage, restart PC, before deleting.

Completely deleted the old folder, attempted to reinstall and got the same error for the 6th time:

Plenty of space on the install drive, so I know it’s not that, but since I have no idea what “Validation Failed” means I don’t know where to go from here. :frowning:

What’s worse, Unity Hub thinks everything installed fine:

And I get this wonderful message when I open my project:

I see you’re using HUB Beta, there’s might be an issue with HUB itself. I’ll move your thread to Hub area.

If possible try using non beta version of the Hub

It’s hard to say without seeing log files, but could you please try this:

  • Uninstall Editor (and remove the installation folder if it still exists)
  • Install Editor with “Android Build Support” module only
  • Add Android submodules

The non-beta version of the Hub doesn’t allow me to set the download location, so I can’t use it as I don’t have the GBs free on my C drive. :frowning:

I am getting the same error, can anyone tell me why is this error showing me while making addressable build
