You forgot to ship libcrypto.dll in your Windows Installer, this means you can't verify your message backup key and decrypt old messages.

To Reproduce
Steps to reproduce the behavior:

1. Install on Windows
2. Try restoring message backup
3. Nothing happens

Expected behavior
Chat backup restores

Additional context

could you share the log info with the error?

Is there an external log?
All that happens now is:

EDIT: nvm, seperate bug, this one happens when \AppData\Local\Temp\chat.commet.app exists while the app is starting, I have to delete that folder before every launch
