Good news, I can reproduce the issue on my side. It only affects the desktop client not the web-ui.

This is because of a Qt limitation as stated in https://doc.qt.io/qt-6/qnetworkaccessmanager.html

Note: QNetworkAccessManager queues the requests it receives. The number of requests executed in parallel is dependent on the protocol. Currently, for the HTTP protocol on desktop platforms, 6 requests are executed in parallel for one host/port combination.

Since we stream PCAP files using HTTP, the GUI cannot make new requests once you hit 6 packet captures.

I will try to fix this soon.
