Win11 Task Manager crashes when closing Task Manager

GDay All,

I have an issue with Task Manager. Whenever I try to close Task Manager it hangs and will not close. Clicking on the close button several times will eventually show the 'not responding' message and it will then pop up a dialogue allowing you to close the program or wait for it to respond.

Also, when Task Manager is open and running, there seems to be a few issues with it, like not reporting events correctly or reporting changes slowly etc.

I have tried several suggestions found on the net and I even tried doing a repair install, but nothing so far has corrected the issue.

Booting into 'safe mode' shows the same behaviour where closing the Task Manager causes it to hang and Task Manager generally misbehaves.

A related issue seems to be File Explorer will occasionally lock up and not allow me to expand a folder (by clicking on the arrow beside the folder name), although it seems to still function otherwise. To correct the issue I need to close and restart File Explorer.

This has been happening for the last 3 weeks or so and I am not sure if it is related to a Windows update or not.

Does anyone have any suggestions or possible fixes for this issue?

Any help would be appreciated.

Reproduction/reason: Hangs due to WlanSvc service as seen in Resource Monitor. Once I stop that service it resumes normally. WlanSvc handles Wi-Fi, and after stopping it TaskMgr works and doesn't display Wi-Fi device. Wi-Fi stops working after killing the service.

How to reproduce: Open Task Manager.

How to bypass: Open Services, stop WlanSvc service.

Steps Taken: Up-to-date Windows, Safe mode, Wi-Fi off, disable, uninstall. Use 32-bit taskmanager (same issue), use Process Explorer (works). Stop offending service discovered from Resource Monitor (resolves temporarily, but leaves me with no Internet). Posted in Feedback Hub.

Summary: Something after 22H2 update prevents WlanSvc from functioning properly causing Task Manager to not function as it enumerates Wi-Fi. This Service is also responsible for the related GetHelp.exe crash and others I posted in Feedback Hub.

Update: Added video demonstrating what happens and how to reproduce the issue.
