New install with Outlook conversion

Hello - I'm trying to transition from Outlook desktop to Thunderbird in Widows 11, but the setup fails (just stops) when I try to import my Outlook pst data. Ive tried the Outlook scan and repair tool - no luck. My file is quite large - about 20GB. Is that the issue? Is there a workaround?

Thanks for any suggestions.
