It seems like the fix available in 4.6.0 is only applying to default path of puppeteer.
Is there any way to apply the fix to the chromium path specified in launchOptions of jsreport.config.json
We had only updated the puppeteer in the 4.6.0. Nothing more. The perm problem is fixed in the new chrome installer as far as I've read the issues in chrome/puppeteer repo. You may have to run that icacls command on your own during the app startup.
