fontforge can not create the font file. Probably the directory is non-existing or not writable.

fontforge.exe --script ./font-patcher --mono --no-progressbars --careful --complete -out "C:\users\username\desktop\" InputMono-Regular.ttf

Probably try without --out. I have no clue how paths needs to be specified with windows :grimacing:

It is very hard to catch all possible ways file creation can fail and fontforge does crash if it can not do it - we can not really prevent that.

[Finii]

Works on my machine:

Closing this, please reopen if changing the path of -out (or dropping that parameter) does not help and you checked that you can write to the output directory.

Here a bit of the fontforge code, that seems to be some unspecified I can not write to disk problem.
