Windows: 'Unknown error', message: "Value of 'password encoded as UTF-16' is longer than the platform limit of 2560 chars

When attempting to authenticate on Windows via, e.g. ak config setup --authentik-url https://authentik.company, I receive the following error after completing authentication in the browser:
Waiting for authentication...
Error running command: failed to register profile with agent

Caused by:
code: 'Unknown error', message: "Value of 'password encoded as UTF-16' is longer than the platform limit of 2560 chars"

Location:
ak-cli\src\commands\config.rs:107:10

This is in both cmd and powershell. I'm able to authenticate with an enrollment token in the user profile authentik.yaml, but attempting to switch profiles results in the error. Let me know if I can do anything to diagnose.

Doing a bit of reading - this is due to the size of the token returned by Authentik, most likely. The Windows keyring store cannot support tokens larger than this limit. Other applications work around this issue by using file-based token storage which may be a solution here. It's not clear to me why the tokens from my installation are this large, so any general troubleshooting advice in this area would be helpful for me and anyone else who encounters this condition. I'm also seeing that chunking into separate credentials in the credential store is a potential option. Ideally, we'd see this supported natively by windows-native-keyring-store.
