I'm sorry it didn't work for you.

Could you check if there are any error messages (press F12 to open the dev tools, then check the "Console" tab) so I can investigate further?

Follow-up:
Thanks for the error messages.
This seems to be an Indexeddb-related issue.
Were you in private browsing mode? (If so, try again in normal browsing mode)
Did you try with a clean user profile?
