Cannot close pre_defined file

Hva betyr 12336 ?

An attempt to close a pre-defined KAREL file (such as CRT/KB, teach pendant, or vision windows) failed. This IO_STATUS error indicates an issue preventing the proper release of these standard system I/O channels. This could leave the resource in an indeterminate state.

• The specified pre-defined file is locked by another process or is in an invalid state, preventing its closure.
• System resources are preventing the proper closing of the file, such as a hung I/O operation.
• The pre-defined file was not properly opened in the first place, leading to an attempt to close an invalid handle.
