I understand current VSCode integration is not ideal but we are trying to address problems. We are using ptvsd debugger provided by ms python extension for debugging purpose. This is an issue with the latest python extension installed in VSCode. You need to downgrade the ms-python extension from VScode to lower version 2019.9.34911.
Please refer to the following similar issue API debugger doesn't work after Oct 2019 update. Go to Solution.
Please make sure to close fusion when you are doing this. Also restart VScode once the extension is downgraded. To verify, you can check your directory on Windows “%HOMEPATH%/.vscode/extensions/” on Mac “~/.vscode/extensions/” this directory should contain only one ms-python extension version 2019.9.34911. If it contains another version please delete that folder also in ‘.obsolete’ file if there is an entry for the ms-python extension you should remove it.
May be with next Fusion release the need of this workaround will not be required and issue with new extension will be fixed. Unfortunately going back to Spyder is not an option right now. Thanks.
