Unexpected error occuring out of the blue

[supremeKAI40]

I have been using this to control fan speed in my Asus Vivobook 14x pro OLED m7400qe laptop. It has been working very smoothly. Until this one evening, when all of a sudden one error keeps coming which has rendered the app useless.

I am using Windows 11 home edition, updated to the latest version

Attaching the error message below:

See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.

For example:

When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
