thank you very much

Please update to the latest version and check if the error still occurs. If yes, please follow the instructions here and upload the full log file: https://github.com/shajen/rtl-sdr-scanner-cpp/tree/devel#debugging

I had the same or similar issue (but I did not saved the errors) when using multiple frequencies. The new build from yesterday seems to be fine so far. (VMWare Player, Ubuntu 22.04.1 and RTL-SDR from GIT) Thank you Shajen! (I think there might be gain issue or changes with the new build, but it is too early to tell - it would be nice to have AGC/Tuner controls for the config)
