A family of Microsoft word processing software products for creating web, email, and print documents.
Are you seeing the Repair Now option? In that case, you may already know that it often fails to work.
Instead, restart your computer and then run an Online Repair of Office. See https://support.microsoft.com/en-us/office/repair-an-office-application-7821d4b6-7c1d-4205-aa0e-a6b40c5bb88b .
P.S. I haven't seen an explanation of why Word crashes like this sometimes. An Online Repair would normally fix the problem, though.
