Hi Dennis,
The problem was resolved after I restarted the machine. The logging becomes normal after that too. Thanks for you help!
I hit another other issues after that, which does not show in my old machine either.
1. When I press F5 (or F7), a window/tab with the name "Build(.process)" jumps out into the editor window. It shows the same content as Build tool window at the bottom. How can I disable it?
2. The above one is a minor issue. What really bother me is when I press F5, the gdb did not go to the breakpoints that I set. In stead, it seems running until I hit the pause button and then it goes to the breakpoint.
3. I also observed some stack_log complains, after which the tool windows at the left side was forced off.
I attached the logs and screen captures for the above issues.
Thank!
Update: I installed 2019 version 2400, which has been used in my old machine. I tried several times on the same workspace. I haven't seen any of the above problems yet. I will keep using 2400 right now.
