Hi,

I had the brilliant idea to do a deploy at around 23:00. It failed and it is now 02:00. In Azure.

An exception is thrown and it complains about uSync content edition which I do not have installed anymore and no references to it. Here is the error message:

Boot failed: Umbraco cannot run. See Umbraco's log file for more details.

-> Umbraco.Core.Exceptions.BootFailedException: Boot failed.

Umbraco version 8.6.3.

I have tried deleting the uSync package completely and everything related to it but I get the same error.

Lightinject is version 5.5.0 and I have tried downgrading to 5.4.0 to no effect.

I have tried to roll back to multiple older release versions of my site but it doesn't work. I have tried azure pipelines deploy, ftp deploy, visual studio app service deploy.

Publishing to a folder and pointing to it locally and viewing it works perfectly. For some reason Azure does not want to play anymore.

Here is the repo and release version if it helps: https://github.com/rasolo/website/tree/release/2.4

Any ideas?
