PHP Xdebug debugging stops working in VSCode at first breakpoint

I am using Wamp on Windows 10 Pro 64bit. Firstly, PHP XDebug based debugging works fine on my normal Core PHP application in Visual Studio Code but when I start debugging a PhalconPhp (MVC) based application it stops at the first breakpoint and doesn't proceed, whatever I try - Continue (F5), Step Over (F10) etc. None of the keys or options work.

I have checked all similar issues and solutions - tried changing port from default 9000 to 9001 in php.ini and launch.json, added all extra configurations suggested in various posts although I am not doing remote debugging. Tried to setup a single and multiple breakpoints and also tried keeping them on various lines at start, middle or end of code.

php.ini

xdebug.remote_enable = 1
xdebug.remote_autostart = 1
xdebug.remote_connect_back=1

xdebug.profiler_enable = On
xdebug.profiler_enable_trigger = On
xdebug.profiler_output_name = cachegrind.out.%t.%p
xdebug.profiler_output_dir ="R:/Temp"
xdebug.show_local_vars=1
xdebug.remote_port = 9000
xdebug.remote_log=R:\Temp\xdebug.log

launch.json

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Listen for XDebug",
            "type": "php",
            "request": "launch",
            "port": 9000
        },
        {
            "name": "Launch currently open script",
            "type": "php",
            "request": "launch",
            "program": "${file}",
            "cwd": "${fileDirname}",
            "port": 9000
        }
    ]
}

There are no error messages. The debugger doesn't move an inch and stays stuck at first breakpoint. I can only restart execution in debugger, none of the other operations (Step In, Step Over, Continue...) work. I also have xdebug.log but don't see anything useful in it.

UPDATE: Debugging is working well for all Php programs including Phalcon with VSCode 1.36.1, XDebug 2.6.1, Php 7.2.14 on Windows 10. I think VSCode and XDebugger have some incompatibility issue for newer versions, but not sure.

In Setting->Debug you should uncheck "Break at first line in PHP scripts" item, this setting is for phpstorm but I think that's same for other IDE.

UPDATE

For VS code:

The launch.json file has the setting "stopOnEntry":true. Change this to false to prevent this. The docs for this can be found code.visualstudio.com/docs/python/debugging#_stoponentry

I started using VS Code debuging php (wordpress) recently. When I enable multiple breakpoints, it sometimes stuck like you described. When I enable only one breakpoint at any moment, it seems worked smoothly. Though it is not without hassle, it is better than no solution. I guess that when mutliple threads hit break points, they all try to talk to the xdebug and somehow deaklocked.
