SOFTWARE/OS VERSIONS

Qt Version: 6.11.1
Kernel Version: 7.1.5-arch1-1 (64-bit)
Graphics Platform: Wayland
ADDITIONAL INFORMATION
QPointer::clear() is not supposed to be dangerous.
The only way this makes sense to me is that if the `this` instance of
`PeerConnector::Private` no longer exists.
Feel free to "RESOLVE" if this doesn't give any useful info. I wish I had asan
enabled at this moment, as I am unable to recreate it.
