vscode: VSCode freezes/blocks at startup

Hello,

VSCode is very long to start, juste showing a blank window for up to 10 sec. Sometimes, I also have a popup window proposing to kill/restart or wait. Also, after VSCode is finally started, after a couple of minutes, it freezes for again few seconds (10-20) before being fully operationnal. This behavior only concern the 1st open window. If I open a new one, no issue. Also, if I close all the open windows, and then open again VSCode, the issue is reproduced.

I have tried tu play with different options like --disable-extensions and --disable-gpu, but without any improvements… I have also tried to fully remove VSCode and the extensions, and then reinstall, but I still have the same behavior.

My system is:
