Cannot sign into Power Automate Desktop - "Sign in to your account" screen blank

Hi All 


Please Assist - I cannot seem to log into Power Automate Desktop with my Work Microsoft Account. It is the only one I use and have not had any such an issue with any other app. I only get a blank screen when I expect to enter my password / credentials

Hi @Jacobus_Toua ,


Can you check the following:


1) Restart and retry

2) Minimal requirements here for PAD are met.

2) Uninstall and reinstall latest version here

3) Anti virus on system or company firewall/proxy blocking it?

4) An environment with a database

Hi @Ahammad_Riyaz - only files I can find 



I deleted the cache files - but no success 😞

Hi @Jacobus_Toua 


Were you able to use PAD before or is it first use?

Check the logs at "C:\ProgramData\Microsoft\Power Automate Desktop\Logs", it might give you a hint of what is blocking you from login. Be prepared to go through a ton of files though.
