I searched and failed to find a exe called mncjywbe.exe, maybe I need more research but please make sure to type it correctly.
Since this issue occurred after installing some other utilities, then I suspect that it is caused by some software conflicts, you can uninstall the newly installed software if possible as a test.
If the mncjywbe.exe means the newly installed software, then install it in a compatibility mode
or boot your system in a clean boot mode to narrow down the cause. please refer to this link:
