+1 on the crashing, the app crashes instantly with the latest update (I just updated, so I'm guessing I'm on the latest version 7.13.0).

To provide a bit more detail than OP, when I open AltTab, macOS instantly pops up with the 'Send a crash report?' prompt, I press Send, then I see the AltTab menu bar icon very briefly and then it disappears.

This is a major bug that renders the app unusable, CC @lwouis .

I tried starting AltTab from command line and it behaves similarly, I have no idea if this output if of any use but here it is:

[christophe-calmejane]

I had the same issue, without the crash report window. Of course, I cannot even auto-update, good thing I checked github for this bug, and this fix. Thanks!
