Hi @AdrianKlinetobe ,
Has this happened across multiple days/logins? The first thing I would suggest is to make sure you are actually logged into your Google account, and make sure it is the right Google account (presumably one provided by your school). If you have more than one Google account, make sure you are not logged into any others. Close all other windows.
Also make sure your browser is up to date. Canvas requires the browser to be on the most recent or second most recent version.
Another thing to try is clearing your cache/cookies/browsing history.
Also note that you have posted on a global Canvas board, not a board within your own school. You may want to check in with classmates to see if anyone else is having similar issues.
