Repro code

private void Test()
{
    GetName();
    GetName();
}

private void GetName()
{
    try
    {
        var folder = @"Plugins\Test";
        //新建插件域，并注明可卸载
        assemblyLoadContext = new AssemblyLoadContext(folder, true);

        var assembly = GetAssembly(@"Plugins\Test\Test.dll", assemblyLoadContext);
        var driverType = assembly.GetTypes().FirstOrDefault(x => typeof(ITestClass).IsAssignableFrom(x));
        System.Console.WriteLine(driverType.GUID.ToString());

        var driver = (ITestClass)Activator.CreateInstance(driverType)!;
        var name = Utility.GetPropertyValue(driver, nameof(ITestClass.Name));
        System.Console.WriteLine(name);
        assemblyLoadContext.Unload();
    }
    catch (Exception ex)
    {
        System.Console.WriteLine(ex);
    }
