dotnet-trace report Missing Symbol for .Net 6 application in container even when pdb files are available

### Description
We have a .Net 6 application running in container with base image mcr.microsoft.com/dotnet/sdk:6.0-jammy. When using dotnet-trace to investigate a perf issue, we found that dotnet-trace reports a lot of functions as "Missing Symbol".

Opening the netrace file in Visual studio does not seem to work either, even when "Load All Symbols" is clicked.

I've checked that the pdb files are in the same directory with the dlls, could anyone suggest the next steps for further diagnosing?
