Mac TurboTax 2024 won't start

The Mac TurboTax 2024 desktop application doesn't start up correctly for me. After launching, it says the application is up-to-date, then it says no tax forms updates are required, then it prompts me to login to my Turbotax/Intuit account. I enter my credentials, but then I just get a screen with spinning blue dots.

If I quit and launch again, it hangs again with a blank screen. The AI support chatbot suggested I delete Intuit-related keys from my keychain and delete preferences from the "Library/Application Support/TurboTax 2024" folder. I did that, but the original problem recurs when I try again. I have no issues when trying to sign in to TurboTax on a web browser.

 

I'm running on an M2 Mac with MacOS Sequoia 15.2. Anyone else encountering this issue, and are there any workarounds?
