I am having the exact same error. I'm an IT support technician (for 30 years) and we upgraded our Quickbooks Pro from 2021 to 2024 last year (desktop version). I do not have access to the old computer and there should be no reason to have to uninstall and reinstall QB. In fact, we just upgraded to a new computer a month or so ago so this IS a fresh install. Apparently the font issue is a glitch (I'm sure a purpose-built glitch forcing you to qbo as usual). Intuit support should release the fonts in a downloadable update.
