Frown (Error) - The data source credentials could not be decrypted

Yesterday I updated to the April version, but it is today that I get the same error as the others. Without opening any files, simply when opening PBI. Since I have many credentials already registered previously, I will do my best not to reinstall PBI, since with a reinstallation all credentials are lost. In case they can be saved (which I would have to investigate) it would surely be of no use, because that's where the problem seems to be.
In any case, you have already commented that uninstalling and reinstalling, the problem is not eliminated. I'm afraid it's a bug from the April version.
