I believe you have helped to turn off my "mad" status LED.
It seems that, Notepad , which we both applied to correct the env file after we found the "bug", is not a perfect solution.
Midification manually env file would always be corrupted again every time a lunched the setup -> user reference and clicked "apply" buttom:( May be the bug plays more playfully in my machine:)
So as a sensient man currently, I decided to uninstall my 15.5 and reinstall my 15.2.
Whatever, thanks very much to your help, really .
BTW,I am not a member of sourcelink, so you might help me to file the bug:)
