Mail crashes immediately upon opening

Hoping someone has an answer. About a week and a half ago, when I click on Mail, it crashes immediately. The other two users on the computer have no issue. I've tried booting in safe mode, opening mail while holding the shift key, resetting the NVRAM, even went as far as reinstalling MacOS. Oh, also tried going into System Preferences/internet accounts, removing the email accounts and re-adding them again after trying to open mail, all with no results. Are there any other suggestions out there? Would really appreciate any help. Thank you
