KeyError: 'bpy_prop_collection[key]: key "TLM_Overlay.png" not found'

I am using Blender 2.93.1 and TLM 0.5.5.0

It worked for a moment but now I am running into this error:

Python: Traceback (most recent call last):
  File "/Users/REDACTED/Library/Application Support/Blender/2.93/scripts/addons/thelightmapper/addon/operators/tlm.py", line 52, in invoke
    build.prepare_build(self, False)

    image = bpy.data.images[image_name]
KeyError: 'bpy_prop_collection[key]: key "TLM_Overlay.png" not found'

location: <unknown location>:-1

I can confirm the file TLM_Overlay.png is present, but it semes to be an issue with the key itself.

On a fresh installation, Windows 10 PRO, blender 2.93.1, TLM 0.5.5, I can conform this is happening and does not allow me to use the addon.

First time I launched a bake, it worked, but the overlay was solid pink, second time this error happens.

I did some digging in the script and it seems like blender calls the image "TLM_Overlay.png.001" instead of "TLM_Overlay.png" . Changing it in the script solves the problem but I guess the cause is somewhere else.
