@erikj79 So I started up a VS2022 debugging session for a java.exe process, and the vcruntime140 debugging information is loaded via the Microsoft Symbol Server anyway, same with debug src. Your VS2022 tools debugging source PATH for the VC tools is also pointing at your local VS2022 include folder.
