Description
- SqlPackage or DacFx Version: N/A
- .NET Framework (Windows-only) or .NET Core: 9.0.201
- Environment (local platform and source/target platforms): Windows x64
**Steps to Reproduce:**
1. clone my minimal repro https://github.com/gfody/SqlClrTest
2. open the solution, VS hangs forever on "Preparing Solution..."

if I check the "Do not load projects" box and open the solution and then load all projects there is no hang.
I captured this log while it hung: [vs.log](https://github.com/user-attachments/files/19200066/vs.log)

Research direction
Start by opening the minimal repro at github.com/gfody/SqlClrTest and reviewing vs.log alongside about.txt. Compare normal solution loading with loading projects after selecting “Do not load projects.” Done means the solution opens without hanging on “Preparing Solution...” when all projects load.
