AX 2009 workflow error when editing user permission

Hi,

I have a problem regarding workflow in AX 2009. We just use the Daily Template in General Ledger workflow configuration. When we are editing the user permission of a specific group, the workflow configuration is throwing the below error.

Infolog for Job Workflow Message processing (5637144829)

Infolog for Task Workflow message processing task (5637171340)

SysWorkflowEventDispatcheronAcknowledgeElement

SysWorkflowEventDispatcherraiseElementAcknowledgementEvent

ClrObject static method invocation error.

Exception has been thrown by the target of an invocation.

When we reinstall the workflow, it can create submit, approve or reject. But after a few minutes, the workflow is throwing the error again and what we have configured is not running. Always having a pending status.

Can anyone help me on this? Thanks in advance!
