Question

Before Big Sur I was able to use launchtl like this:

plst file:

Program
/Users/michael/Downloads/Python/scripts/removeLogs.sh
ProgramArguments

    commandLineArgument

StartCalendarInterval

    Hour
    0
    Minute
    0

StandardErrorPath
/Users/michael/Downloads/Python/scripts/removeLogsErr.log
StandardOutPath
/Users/michael/Downloads/Python/scripts/removeLogs.log

commands: // load the LaunchAgent launchctl bootstrap gui/501 com.cronjob1.plist // immediately start the LaunchAgent launchctl kickstart -k gui/501/com.cronjob1 // unload the LaunchAgent launchctl bootout gui/501 com.cronjob1.plist

now I get errors I have no clue about: Bootstrap failed: 5: Input/output error

can anyone help?
