Migration Assistant hanging

I"m trying to migrate from my iMac(2019) to a new M4 Mini. I'm connected via Thunderbolt and the Migration Assistant is stuck. I've restarted it a few times and it always hangs at the same file count. Any tips to get this migration going? https://preview.redd.it/d7q8z34acg7e1.jpg?width=3024&format=pjpg&auto=webp&s=f4e84533a10b243061f907b51968266ae9b73285
