Windows screen grab gets saved as a list

[ReKylee]

When I try to screen grab using WIN + Shift + S, I can't paste the image at all.
Here's the original error:

line    1:
E5108: Error executing lua Vim:Error invoking 'python_execute' on channel 3 (python3-script-host):
Traceback (most recent call last):
  File "<string>", line 1, in <module>
    import sys; sys.path = [p for p in sys.path if p != ""]; import neovim; neovim.start_host()
    ^^^^^^^^^^^^^^^^^^^
  File "C:\Users\<USERNAME>\AppData\Local\nvim-data\lazy\pastify.nvim\python3\pastify\main.py", line 90, in paste_text
    img.save(img_bytes, format="PNG")
    ^^^^^^^^
AttributeError: 'list' object has no attribute 'save'

I've tried fiddling with that function as such:

 img = ImageGrab.grabclipboard()
# ImageGrab.grabclipboard returns either a: Image, List of file names or None (text)
if isinstance(img, Image.Image):  # Check if clipboard contains an image
    img_bytes = BytesIO()
    img.save(img_bytes, format="PNG")
elif isinstance(img, list):  # Check if clipboard contains file paths
    self.logger(f"Clipboard contains files: {img}", "INFO")
    return
else:
# Handle non-image content as text
    if after:
        vim.command('normal! "+p')
    else:
        vim.command('normal! "+P')
    return

and here's the output I get:

Clipboard contains files: ['C:\Users\<USERNAME>\AppData\Local\Packages\MicrosoftWindows.Client.Core_cw5n1h2txyewy\TempState\ScreenClip\{2B604A04-454F-4548-9661-5D1DCE676C9A}.png']
