ESP32 S2 SAOLA 1R ND… IDE compiling Problems.

Hello everybody, i have a new ESP32 S2 SAOLA 1R ND board nere on my Desk. I made some projects with ESP8266 and now Iam going to try the ESP32. In Standard IDE the S2 is not working, so iam looking for help. I found this great Website and a very detailed Installation Guide , which make me very fast and easy a Guide to install all Stuff for the S2 board. SO, on this point, many thnaks for the work for making this guide. Now I Have all doing like descriped and start to comile and upload the first sketch. The scetch is nearly nothing. I Do only, make new Sketch. The Basic. Then I select the ESP32S2 Dev Modul  and try to compile.... The  Arduino IDE is now compiling and compiling and compiling...... and do nothing..... What could it be  ?  I Have Win10 64 Bit, and all steps make like in the instructions here. Any Ideas ? Best regards Rainer
