MsBuild ignore TransformWebConfigEnabled parameter

For some reason MsBuild tag my obj\web.config as ReadOnly. I trying several time to find a workaround but without success.

ServiceApi failed with 1 error(s) (6.9s) → output\
    C:\Program Files\dotnet\sdk\9.0.203\Sdks\Microsoft.NET.Sdk.Publish\targets\TransformTargets\Microsoft.NET.Sdk.Publish.TransformFiles.targets(50,5): error MSB4018:
      The "TransformWebConfig" task failed unexpectedly.
      System.UnauthorizedAccessException: Access to the path 'D:\Projets\output\Web.config' is denied. at System.IO.FileSystem.CopyFile(String sourceFullPath, String destFullPath, Boolean overwrite)
         at Microsoft.NET.Sdk.Publish.Tasks.TransformWebConfig.Execute()
         at Microsoft.Build.BackEnd.TaskExecutionHost.Execute()
         at Microsoft.Build.BackEnd.TaskBuilder.ExecuteInstantiatedTask(TaskExecutionHost taskExecutionHost, TaskLogging
      Context taskLoggingContext, TaskHost taskHost, ItemBucket bucket, TaskExecutionMode howToExecuteTask)

At first it seem, after I track the file with Process Monitor, that is MsSense is locking the file. I add some exclusions to prevent MsSense to lock the file but without success.

After I try to avoid the task TransformWebConfig by:

• Set the parameter TransformWebConfigEnabled to False (in project file, also with a /p:). MsBuild ignore the parameter
• I deleted all my Web.Release.config. Nothing TransformWebConfig it still triggered

It seem this error only happened with the SDK version of my projects. Old school project dont have this issue.
