[BUG] agent cannot load the probe

[ysj2018]

APM Agent version

elastic_apm_profiler_1.30.0-win-x64.zip

Environment

Operating system and version:
windows 10 and Installed the built-in IIS components
./net framework 3.5(包含./net2.0\3.0)
./net framework 4.8 advanced services
.NET extensibility 3.5\4.8
ASP.NET 3.5\4.8

I compiled the same codebase using（It only includes an operation to access Baidu using HttpClient） .NET SDK versions 6.0.136, 5.0.408, and 3.1.426 respectively, for testing purposes

dotnet build
dotnet publish -c Release -o ./publish

1.I placed the compiled package in the specified physical path directory for the IIS website.
2.Started the application and it was accessible normally.
3.However, I added environment variables using web.config. The specific configuration is as follows:

4.After restarting IIS, the application was still accessible normally, but I found that the probe was not loaded. Are there any steps I did wrong? 5.I also tested configuring the above settings directly using system environment variables, but the probe still wasn't loaded. What could be the possible reasons?

I was hoping to see the probe being loaded, but after testing, I found that the application was functioning normally and I could access it through the port configured in IIS. However, there was no sign of the probe being loaded.

The parameters for the environmentVariable node that I configured in the web.config file are mainly as follows:
ELASTIC_APM_SERVICE_NAME=dotnettest
COR_ENABLE_PROFILING=1COR_PROFILER_PATH=E:\IIS\agent\elastic_apm_profiler.dll
ELASTIC_APM_PROFILER_HOME=E:\IIS\agent
ELASTIC_APM_PROFILER_INTEGRATIONS=E:\IIS\agent\integrations.yml
ELASTIC_APM_SERVER_URL=localhost:8200
ELASTIC_OTEL_LOG_LEVEL=trace
ELASTIC_OTEL_LOG_DIRECTORY=E:\IIS\agent\logs
ELASTIC_APM_APPLICATION_PACKAGES=E:\IIS\ddd\
