SubSelect seems to hang/crash MPV.

[AziRizvi]

MPV Version: v0.38.0-743-gad7976c3 Script Version: Git Master Platform: Windows 10 22H2

Both the issues described below go away when I remove the script from the scripts directory.

Video of the first issue: (If I'm playing any video and I close MPV, this is what happens, the MPV window hangs and then I have to kill the process via task manager.)

Video of the second issue: (If I'm playing a video and I use my mpv keybind for playlist-next or playlist-prev the MPV window hangs as before.)

Upon further testing, I can confirm that I can recreate this issue on the latest MPV build by Shinchiro (v0.39.0-26-gc3d9243a)

This issue only seems to be happening when SimpleHistory by @Eisa01 is also in the scripts folder. (https://github.com/Eisa01/mpv-scripts)

I'm not sure which script is exactly the culprit here since standalone, they both work absolutely fine, the issue only seems to happen when they're both in the scripts folder.

I am also experiencing this issue, specifically when using external subs it seems.

I use mpv-sub-select, uosc (with thumbfast) and chapterskip.

To troubleshoot, I purged the scripts directory and added each one back one at a time. I only experience this issue when I add mpv-sub-select, even if it is the only script present.
