Users who recently upgraded to Windows 11 24H2 have begun to experience this problem. It is brought on by a Windows activity Scheduler activity that invokes a PCASVC.dll entry point that is no longer present in the most recent Windows upgrade.
This problem may arise because Microsoft may have neglected to delete the task from the Task Scheduler, which is why it keeps calling the entry point. Many users have expressed concern over this problem, despite the fact that it just results in the display of the error message.
The Program Compatibility Assistant Service (PcaSvc), commonly known as PCASVC.dll, is in charge of identifying and resolving incompatibilities between outdated software and the most recent version of Windows.
PCASVC.dll shouldn’t be corrupted because it is an essential file connected to the Program Compatibility Assistant Service. Otherwise, this error can result.
In addition to the previously listed reasons, the error might also show up if the PcaSvc service terminates its background operation. We can now address the problem’s solutions since we have a better understanding of its causes.
