NETSDK1144: Optimizing assemblies for size failed .NET 7

I have upgraded a Blazor client app from .net 6 to .net 7
and I'm getting this while building a container image

Error NETSDK1144: Optimizing assemblies for size failed. Optimization can be disabled by setting the PublishTrimmed property to false.

I am using this in my DockerFile
FROM mcr.microsoft.com/dotnet/sdk:7.0 AS base

Adding
PublishTrimmed false PublishTrimmed

to the blazor client project file does "fix" the issue, but im not really sure what the actual issue is?

Refers to the error, with no information.
