Error in PS_PRCSRUNCNTL, "Cannot insert NULL in PS_PRCSRUNCNTL"

I'm running my process from my run control page, but when I click on run, it throws error. On checking the logs, the error is "PSAPPSRV.2619571 (6164) [2025-03-11T05:44:28.661 PS@205.164.130.250 (CHROME 133.0.0.0; WIN10) ICPanel] g6IrDOigyd5wDQ 7021987658688607233 PS (3) File: /vob/peopletools/src/psppr/ramupd.cppSQL error. Stmt #: 1092 Error Position: 0 Return: 1400 - ORA-01400: cannot insert NULL into ("SYSADM"."PS_PRCSRUNCNTL"."LANGUAGE_CD")
Failed SQL stmt: INSERT INTO PS_PRCSRUNCNTL(OPRID,RUN_CNTL_ID) VALUES(:1,:2)"
I didnt write any statement like PS_PRCSRUNCNTL. Can anybody tell me how to resolve this?
