I tried below step to run scheduled task on plesk windows server, but no luck
C:\Program Files (x86)\Parallels\Plesk\Additional\PleskPHP7.4\php.exe
C:\inetpub\vhosts\mydomain\httpdocs\artisan schedule:run >> /dev/null 2>&1
I have resolved this issue by selecting "Run a PHP script" instead of "Run a command" task type and added artisan path in Script path field and schedule:run
in argument field.
