Immediate solution to try: Use a mail client to access your mailbox with IMAP or POP3; GMail may be more tolerant that way. Long-term solution: Stop using Google. Why? Not just because of this type of shenanigans, but because Google spies on you: * It keeps a copy of all of your correspondence, even if you delete it. * (Rephrased) The US National Security Agency (NSA) has gotten access to much of your correspondence, by tapping links between Google's data center; it may still have such access today and Google's extent of collaboration with this is not known for certain (to me anyway). * It uses your correspondence and other information about you allow commercial companies to manipulate you with advertisement. (The NSA part was verified by Edward Snowden's revelations, several years back; see: https://www.washingtonpost.com/world/national-security/nsa-infiltrates-links-to-yahoo-google-data-centers-worldwide-snowden-documents-say/2013/10/30/e51d661e-4166-11e3-8b74-d89d714ca4dd_story.html https://www.washingtonpost.com/world/national-security/nsa-i... for example) Now, no third-party mail service is perfectly safe; but you should want one which is at least somewhat-safe, and that doesn't treat you unfairly. I won't make specific recommendations, but I've personally had decent experience with ProtonMail (Switzerland) and gmx.com (Germany).
