Excel no more working

Hello,

Starting two days ago, I have many problems with Excel (Word and Outlook are still working correctly):

• If I create a new document, then want to save it locally, nothing happens when I click the Save button.
• If, for saving, I try to click on "More Options" and then click to "Browse", nothing happens.
• If I right-click on a cell and select "Cell Format", or I click on the ribbon for the paragraph dialog box", Excel crashes.

When crashing, the event viewer registers:

Faulting application name: EXCEL.EXE, version: 16.0.12430.20050, time stamp: 0x5e1570bd
Faulting module name: unknown, version: 0.0.0.0, time stamp: 0x00000000

I've already tried the following, but the problem is still here:

• Repair Office 365 (fast)
• Repair Office 365 (online)
• Start Excel in safe mode
• Disabled all the Excel add-in
• Create a new user on my PC and starting Excel from the new account

As the problems happens with a new document, the problem is not related to the content of the document.

Does anyone has a solution or something else to check or test)
