Error and Screencast Keys stop being displayed when using measurement tool

[GesaP]

• OS: [ Windows]
• Blender version: [2.9]
• Add-on version: [3.0.0]

After some actions the Screencast Keys stop being displayed. Confirmed is trying to use the measurement tool, I have seen it in at least one other occasion (though I am not sure which action did this there)

Error says:

Traceback (most recent call last):
  File "C:\Users\MyName\AppData\Roaming\Blender Foundation\Blender\2.90\scripts\addons\screencastkeys\ops.py", line 587, in modal
    event_type = EventType[event.type]

    return cls._member_map_[name]
KeyError: ''

location: <unknown location>:-1

Blender throws this error and the screencast keys stop being displayed. They start being displayed again after un-ticking and ticking the activation box once.

Apparently fixed in 3.3. Thanks!
