Running 3.4.8 or 3.5.0 same issue appears, 3.4.6 I had no issue. Installed on VM and on my (company) Windows 10 laptop. All features seem to work, issue appears with these settings: writing in ringbuffer of 3x files on my WiFi connection, and manually stopping capture after at least 4 files are filled. I have a Capture Information screen active. If things are going fast, then I can stop and close wireshark without issues, but when capture seems to take a bit more time, maybe when rolling files, it freezes when trying to stop capture screen (but not Capture Information screen). It jumps in menu bar to 'does not respond', and have to kill Wireshark. Hard to simulate and find the exact conditions... still working on it... .
