So first of all I have the latest QB version, the latest windows updates and I have installed, repaired, des-installed and reinstalled QB again. My version is desktop pro 2021.

If i try to email someone, it just freezes for a minute and quicks me out of QB, if I go to preferences ->send forms same thing, QB closes completely. 

I'm not sure if related or not but my logo is gone from invoices and estimates.

no error screen at all.

I have been trying everything for hours, even the chat support, I got nowhere.

I was using gmail to email people and no problem for months, I'm not sure what changed, and even if I wanted to change my email provider, I can't access to that section on preference to make any changes.
