Qt Version: 6.8.0
Frameworks Version: 6.7.0

-- Information about the crash:
I configured the office 365 email account from my university using EWS (imap is not working as it needs oauth2 identification).

At first, everything seems to work fine until it tries to synchronize a folder with almost 30k emails in it, which ruins the experience from there on (synchronization stuck)

Not sure this is because an element in particular or because the long list of elements.

In addition to the backtrace I paste below some messages that appear in the terminal for the case they are useful (some of them appear repeatedly):
