Function rc522_destroy should not be called inside of rfidtag_handler because it is in the same task. You can set some type of flag (e.g. bool variable) inside of rfidtag_handler and then in while loop inside of app_main check that flag and call rc522_destroy function.
Than you very much for your kind support. Now solved the problem. I am still getting small problem after 4 or 5 consecutive scans.

Confirming taskterminated before free(hndl) solved the above issue.Thanks again abobija ji.

Glad it helps. Good luck with your project.
