Happened to me before and solved with a windows reinstall (something I’d like to avoid right now).  
There are no log files and no Windows event log entry. When I start Slicer nothing happens. But if I log in with a different user, it starts flawlessly.  
I’ve already tried desinstalling and reinstalling Slicer, but doesn’t help.

@Nayra_Pumar, maybe there is a problem in the settings? does it help if you start Slicer with the `--disable-settings` flag?

I’ve also noted that the very latest Slicer (Slicer 4.13.0-2021-10-04) does not start due to _Qt5MultimediaWidgets.dll was not found_ error. This is caused by a change that we made yesterday and we’ll fix this error in tomorrow’s release. Until then the installer that created from the day before can be downloaded from [here](https://download.slicer.org/?date=2021-10-04).
