Postman can't be opened properly

I'm trying to open my newly installed Postman when an error occurs which says something like this:

**Could not open Postman**
Error: Migration: IndexedDB schema migration failed. IndexedDb was not upgraded succesfully after `dexie.open`.
Please try restarting the app. If the issue persists, please refer to http://go.pstmn.io/troubleshoot-could-not-open

As it says, the error really persists. The website above only provides suggestions like "reinstall the app" "upgrade the app", which are not really helpful. And as I dig into the Internet, it occurs to me that such error hardly happens (found nobody have the same question like me).

"IndexedDb" was mentioned in the error message, and I just know (from the Internet) that it's a nosql database provided by explorer. Maybe the problem can be solved by reinstalling the database, I guess?

I'd be really appreciating for your help! (And forgive me if I've made any gramma mistake above)
