The formatting getting stuck is likely due to another system blocking the formatting operation. C_Cpp.loggingLevel is available as a user/workspace setting (not workspace folder). If cpptools is using CPU, can you attach a debugger to get a call stack for the thread that appears to be doing work? https://github.com/microsoft/vscode-cpptools/wiki/Attaching-debugger-to-cpptools-or-cpptools%E2%80%90srv

I can't activate the debugger to check if cpptools executed correctly but I used activity monitor to get sum sample as follow hope this would be cpptools call stack sample.txt

The call stacks doesn't show any formatting, but it shows IntelliSense process creation. Are you able to wait for IntelliSense to be finished updating before running the format command? It also shows it's trying to use recursive includes, so you may want to remove any paths with "**" from your include path to stop using recursive includes, which could be faster.

@sean-mcmanus Recently I have been facing the same problem: formatter stuck when saving (I have auto save and format on save active) and intellisense stuck in the flame icon forever (hovering a variable prints loading...). I don't have a step by step guide to repro the problem because it doesn't happen always. The only thing I do is: edit code and then cmake run (with the cmake-tools ext). Sometimes the bug appears sometimes not.

Here is my call stack (I couldn't get it with the vscode - launch.json guide so I used the lldb one):
