Update via git clone without any problems (windows runtime). I tried new functionality with your T_PLC and your Time_Test program. If I open the Monitor page, I get the following error message.
Internal Server Error
The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.
Compilation and starting the runtime causes no errors.
If I could help with more information, please let me know.
