I solved it like this: I downloaded fluid version 12 https://www.nuget.org/api/v2/package/Fluid.Core/2.12.0
renamed the .nuget package to .zip and opened the file.
Inside there is the Lib folder and I went to the fluid.core.2.12.0..zip\lib\net8.0 folder and copied the files to C:\Program Files (x86)\Rico Suter\NSwagStudio\Net80
and it worked.

I have the same issue, it started after I upgraded to version 14.2.0.0 from version 14.0.0.0. I had to copy the file to the C:\Program Files (x86)\Rico Suter\NSwagStudio\Win\ folder because I'm using the WinX64 runtime. Seems to me that the setup is missing that file.
