Even if I delete the cache or reinstall, I still can't sign in.
I get the error message "An error occurred while communicating with the Microsoft Power Automate cloud service. Please try again, and if the problem persists, contact your administrator."
The cause seems to be that the msalcache.bin3 file that is referenced when signing in is missing, so there is no information to reference, but no matter how many times I reinstall and sign in, it is not generated.
Do you know how to generate the msalcache.bin3 file?
