Remove -serial studio in Debug configuration, then debug again

Could you show the case in your settings?

Please check the binding keys of formatter in your IDE.
The default is Ctrl+Shift+F, and you may ensure it was not occupied by another application

Thanks for your feedback,
We need to do some special settings in our server，
I will notify you as soon as possible

Finally, with Varun's help, this issue was solved.

If you guys meet this kind of problem,
please open studio.ini which was located in the root directory of RT-Thread studio,
and then, modify
-Dorg.rtthread.studio.browser.systemdefault=false
to be
-Dorg.rtthread.studio.browser.systemdefault=true

With all operations above, open RT-Thread studio again

Welcome, varun.

Would you like to show me the content of studio.ini which was located in the root directory of RT-Thread studio?

And then check the value of -Dorg.rtthread.studio.isGlobal；if it's false, please set it to be true.
