After TB was hanging (with script kill dialog) I killed it. As a result TB was unusable. I tracked it down to the EWS plugin. It seems, that it happens, if there is any data in the exchange-data folder in the profile. After deleting the content of that folder TB starts normally and shows (after a while) all my calendar entries from the Exchange account. I am using TB 52.1.1 (32 Bit) on Windows 10 (64 Bit) with Lightning 5.4.1.1 and EWS 3.9.0.
