cortex-debug: IAR executables debugging no longer working

Hi there, 2 days ago everything was working fine, then i think the microsoft c++ extension updated and since then i cannot get cortex-debug to work. The debug console does not update when i start debugging and there is no entry under the output->remote adapter that i used to be able to see when there was a problem with segger. Furthermore I have code insiders installed separately and when the issue presented itself in this version of code I was still able to debug using the insider version with the same workspace and output file. Then the cpp plugin updated and it all stopped in my insiders copy too. I have removed the cpp extension and re-added it but that has not resolved the issue (same with cortex-debug)

code 1.43.2

my launch is like this

{
      "name": "App",
      "cwd": "${workspaceRoot}",
      "executable": "${workspaceRoot}\\app\\${config:iarvsc.configuration}\\Exe\\${config:iarvsc.configuration}.out",
      "request": "launch",
      "type": "cortex-debug",
      "svdFile": "${workspaceRoot}/STM32F4/STM32F40x.svd",
      "servertype": "jlink",
      "device": "STM32F407VE",
      "interface": "jtag",
      "showDevDebugOutput": true,
      "runToMain": true
    },

Edit: I have just enabled showDevDebugOutput i can see the following in the debug adapter: 000000016: Reading symbols from 'C:\xx\yyy\(folder with brackets)\Exe\(filename with spaces and brackets).out' but it just sits there and doesn't proceeed. Any ideas? Thanks for you efforts!
