I can't possible help with such little information. Please provide clear repro steps as per the issue guidelines

We also had this after upgrading to .NET 7, this resulted in:

Unhandled exception. System.IO.FileNotFoundException: Could not load file or assembly 'Swashbuckle.AspNetCore.Annotations, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.

The stack trace indicates that this happens at time of calling AddControllers in our code.

We had trimming on <PublishTrimmed>true</PublishTrimmed> with copyused mode <TrimMode>copyused</TrimMode>.

And these 2 packages:
<PackageReference Include="Swashbuckle.AspNetCore" Version="6.4.0" />
<PackageReference Include="Swashbuckle.AspNetCore.Annotations" Version="6.4.0" />

After turning trimming off, things worked fine again. For some reason this was not an issue in .NET 6 with the same package versions.

I believe this is fixed in DotSwashbuckle
