Thanks for reporting the issue. This is fixed in the upcoming release.
Until then, as a work around you could start station in daemon mode using flag -d (see station --help for more details). This will cause station to start in the background, and additionally it will fork into a child-process such that the parent remains the daemon control process which restarts the the child when it exits for some reason. In the log you will see something like:

2020-05-14 10:55:23.175 [any:CRIT] Radio device '/dev/spidev32766.0' in use by process: 17882
2020-05-14 10:55:23.596 [SYS:ERRO] DAEMON: Station process 17882 died (exit code 0x1E00)
2020-05-14 10:55:23.606 [SYS:INFO] DAEMON: Station process 17943 started...

In order to be able to inspect the log in daemon mode you should specify a log file inside station.conf, like this:

...
    "station_conf": {
        "log_file":  "/var/log/station.log",
        "log_level": "DEBUG",  /* XDEBUG,DEBUG,VERBOSE,INFO,NOTICE,WARNING,ERROR,CRITICAL */
        "log_size":  10000000,
        "log_rotate":  3,
         ...
    }
...
