Resolve Uno WebAssembly Publish Failure

My Uno Platform app targets WebAssembly and runs perfectly in Debug for both WebAssembly and desktop. The moment I switch to Release and hit Publish, the build stops and nothing usable is produced—no meaningful error, just an unsuccessful publish. The goal is simple: make the project compile and publish cleanly so I can drop the output onto my IIS server.

What I need from you
• Inspect the existing solution and pinpoint the build or MSBuild configuration that breaks the Release publish.
• Apply the necessary fixes—package versions, project settings, linker options, or whatever else is blocking it.
• Produce a working publish folder ready for IIS, then document the exact steps so I can replicate the process on my own machine.

Tools & experience that will help
• Solid knowledge of Uno Platform and .NET WebAssembly builds.
• Comfort with Visual Studio, MSBuild, and typical Release vs. Debug pitfalls.
• Experience deploying WebAssembly apps to IIS.

No UI tweaks or new features—just get it to compile, publish, and deploy smoothly. I can provide the repo and, if needed, arrange a brief screen-share session.
