What happened more exactly? Did you get a standard Windows crash log? If so, maybe try checking for any errors in the event viewer (https://docs.microsoft.com/en-us/host-integration-server/core/how-to-check-the-windows-event-logs-for-errors1).

There's these ominous lines in the log:

[update:14164] [20:29:11] [WARN] Failed to locate app manifest (This application is missing a package manifest (.nuspec) or it could not be parsed.), trying legacy package resolution...

[update:14164] [20:29:13] [ERROR] Start error: Unable to find executable to start: '"C:\\Users\\necos\\AppData\\Local\\osulazer\\current\\osu!.exe"'

But apart from that last one I'm not sure if they're relevant. We're definitely packing a nuspec (well... Velopack does that itself):

Can you start the game fine a second time?

There's these ominous lines in the log

the package file does exist, the current folder is gone so the app won't run

Can you start the game fine a second time?

no, neither the updater nor the osu!.exe in the root folder will run

Maybe cc @caesay

https://github.com/velopack/velopack/issues/355 is this the issue that cause this situation?

is this the issue that cause this situation?

no. that issue is a linux issue. you are not on linux.

Update.exe process appears to have crashed during the update.

The last log printed was "Backing up current dir to C:\Users\necos\AppData\Local\osulazer\packages\VelopackTemp\tmp_7zRRNYZ8Kx06lNHE" - and then nothing.

What's weird is that this binary is written in Rust, so there shouldn't really be unhandled crashes (without log messages) in general.

@necocat0918 please check if there's an error in event viewer.
