IIS application stopped after install the .Net agent

We have installed the on premises controller(4.3.8) and we start deploying the .Net agent in IIS(8.5)server,

after complete the agent deployment,agent starts running but the application got shutdown and when i try to start again it stopped,after uninstall the agent then only the application started.

Actually we start this deployment in production environment.We have license with 9 .Net servers and 6 DB servers.

We identified the following log in IIS event viewer logs

Line 142: Error 2/21/2019 3:45:26 PM Application Error 1000 (100) "Faulting application name: w3wp.exe, version: 8.5.9600.16384, time stamp: 0x5215df96
Line 153: Error 2/21/2019 3:45:26 PM .NET Runtime 1025 None Application: w3wp.exe
Line 177: Error 2/21/2019 3:31:09 PM .NET Runtime 1022 None .NET Runtime version 4.0.30319.0 - Loading profiler failed. COR_PROFILER is set to an invalid CLSID: 'AppDynamics.AgentProfiler'. HRESULT: 0x800401f3. Process ID (decimal): 11940. Message ID: [0x2502]
