"The input is not a valid Base-64 string as it contains a non base-64 character, more than two padding characters, or an illegal character among the padding characters".

Question

Hello, suddenly this error message appears: "The input is not a valid Base-64 string as it contains a non base-64 character, more than two padding characters, or an illegal character among the padding characters". The error appears as soon as I start the application, and if i close it, the whole application closes too. Please advise. Thanks in advance.
