After some further testing - turns out that if I boot into "safe mode with networking", CCleaner works normally. The bug only happens in standard safe mode (without networking). Still, having network enabled shouldn't be a requirement to use CCleaner in safe mode.

I know this is a very old topic, but just wanted to report that this bug is STILL present in CCleaner v5.61... with Windows booted in safe mode, CCleaner will always auto close when analysis stage reaches 100%. No problems when booted in normal mode using the same cleaning settings / options. Tested in 2 different PCs with Windows 8.1 x64 and Windows 10 1903 x64, same behavior. A system cleanup / maintenance software that can't be run in safe mode? This is absurd. If at least the auto close happened only after the cleanup procedure, it wouldn't be so serious, just an annoyance - but as it is, this is a serious functionality-impairing bug. Please Avast/Piriform, get around to fixing this.
