Ok, the fact that incognito works suggests that clearing site data (cache, cookies) from your regular browser might also do the trick; this will hopefully need to be done only once.
Your logs tell me that you are using Chrome. In Chrome, go to chrome://settings/content, then delete data for adobe.com (you can use the search field on the top right).
Let me know if that does/doesn't help.
Thanks
