Rider showed running error when debug, and cannot debug. But debug was working fine usinng visual studio 2017. And Run was ok on Rider.

Error message: class com.intellij.util.ui.components.BorderLayoutPanel cannot be cast to class com.intellij.ui.OnePixelSplitter (com.intellij.util.ui.components.BorderLayoutPanel and com.intellij.ui.OnePixelSplitter are in unnamed module of loader com.intellij.util.lang.PathClassLoader @6debcae2 Rider version: 2022.2.4.win & 2022.3.2.win

Please tell me how to fix it. Much appreciate .

Hi Jasonnotcai! 

It seems like you are facing an old rare issue. Could you please try the following:

  • Use double Shift (Search everywhere) -> Actions -> Registry
  • Open Registry and uncheck debugger.new.tool.window.layout there 
  • Then turn Immediate window on via this action or via action on the debugger toolbar:
  • After that, roll back "debugger.new.tool.window.layout" to checked. 

 

I hope this helps! Please let me know how it works for you.
