To solve this, you can just run these commands in your terminal:

sudo find /workspaces/ -type d -exec chmod g+rw,o+rw {} \;
sudo find /workspaces/ -type f -exec chmod g+rw,o+rw {} \;

here find will locate all the files for the -type d and folders for the -type d and then execute the command chmod g+rw,o+rw {} on each one of them, while replacing {} with the location of the file/folder found by the find command.
