I just got backblaze working on a fresh install, and by the looks of it you’re on older version of discourse - the version of ruby in your stacktrace is 3.3.0 and on mine it’s 3.4.0. Not sure if it’d make a difference, as the versions of aws-sdk-core and aws-sdk-s3 gems seem to be the same, but I thought it may be worth pointing out.
