Just remembered that this is very similar to an old bug I reported (#350)

What I'm confused about is there is somehow a space after the drive letter, which...can't be there

-filter_complex "[0:0]subtitles='D\ :\\Users\\Maddie\\...

I think if it's removed so it's D\:\\ instead it should work, but I honestly don't know how it got to that point to start with (somehow in FastFlix, not something you did). Looking at it but is tricky

It only started happening sometime after v5.5.4 if that’s of any help to you.

Just discovered that this problem is not limited to subtitles. If seems that any pathname with "\\" qualifiers that that "wrap" across lines is affected.

For example:

D\:
\\PathName\\File

Becomes "D: \PathName\File" (which equates to "D: \PathName\File" during processing.

This happens frequently.

I think that I've found the "Perfect Storm" that causes the issue...

1: Pathname is long and contains sub-directories
2: Pathname has "\" qualifiers that that "wrap" across lines
3: Usually HDR10+ source (but not always)

This happens frequently when the queue is saved and re-loaded.

I hope this is of some help.
