Lost all contacts

Just lost all my contacts in my Android phone.

Galaxy S10, Android v12.

Tried different contact apps, tried rebooting, tried googling (yes, Internet, I have the apps set to display all contacts).

Tried restoring contacts, and it says 0 restored.

They’re still in Gmail, so I tried exporting them and importing them onto my phone, but the phone won’t let me select the file.

I’m thinking I’m going to have to do a factory reset.

Any other suggestions before I bite three bullet and wipe the device?
