"Unable to extend cache - no space on device" error

[TheInsane101]

Describe the bug
One of the svg files inside a folder of svg files won't convert to png for some reason due to "not enough space on device," even though I have more than enough space.

To Reproduce

1. Download the All Country Flags zip from https://hampusborgos.github.io/country-flags/
2. Extract the file
3. Go into the svg folder, select all the files inside it and set it to convert to png.

Expected behavior
I expected all the svg files to successfully convert to png, but instead, the gu.svg file (of the Guam flag) got the error I described above, even though it is only 16 KB (other files are 40 - 50 KB) and all the other svg files converted successfully.

Screenshots and Logs

Please note that I updated the converter program to 2.1 after this screenshot was taken and I reattempted the conversion, selecting only the gu.svg file, and it still failed with the same error.

Here's what the logs say:

Desktop (please complete the following information):

• OS: Windows 10 21H2 LTSC, latest updates installed (I know it looks like 7 or 8, but I installed mods to theme the look of 10)
