Can't login to hotmail.com

Hello,

I have windows 64-bit home 1903 and I can't login to hotmail with latest versions of Slimjet/Firefox/Chrome browsers. The browers freeze and the screen turns white as soon as I want to enter my login.

This happened with Sandboxie 5.31.2 and after updating to 5.31.4 the problem still occurs.

Outside sandboxie I can login to hotmail with each browser.

I also get an message error at irregular times:

 

Can you help me out?

Thanks!
Dirk
