Have you checked the original m2ts with Mediainfo (View > Text)? What does it read under Framerate and what does the MKV?

Weird, it works just fine for me on Windows 10. You can bypass Windows Defender to execute unrecognized apps, so maybe you should upload BatchMKV to virustotal and take the risk.

Have you tried MakeMKV Batch Converter?

Have you searched the forum for 'batch'?

As the name suggests BDSup2Sub converts only bitmap based subs to other bitmap subs, there's no OCR. There's two tools you can use (on Windows) that do the job well: DVD Subtitle Extractor 1.0.3.2 Unlike the name suggests you can also open PGS subs extracted from BDs/MKVs. Subtitle Edit Subtitle edi...

I don't know if it's worth the effort but you could download a windows evaluation ISO from Microsoft and set up a virtual machine with Virtual Box on your Mac. You don't even need to activate it to make BDInfo work in it.

BDInfo?

Please see attached screenshot.

In Mediainfo simply select View -> Text and you can paste it here. No need for screenshots.

Have you searched the forums? This has been discussd to death, recently with Game of Thrones subs. This should apply to Plex as well.

IIRC one of the subtitles has these infographics. You could verify this by demuxing all subs from the m2ts with TSMuxer and opening them in BDSup2Sub.

You can try to re-author them with DVD Shrink.

JMkvpropedit v1.4.3 - Batch GUI for mkvpropedit

allows you to set flags and generate a command-line. I'd start with this but if it does not work, I have a batch on my system somewhere that could help as well. Gonna check it out if you don't make progress.

'app_DefaultSelectionString="-sel:all,+sel:(eng)' deselects everything and then selects all english tracks. What sub folder are you talking about? Forced subs vs regular sub has been discussed to death on this forum.

As recently discussed in the thread 'Botched subtitles when ripping Avatar' it's usually the other way round: the forced subtiles are stored in their own track where they're not flagged as forced and as such are not recognized by MakeMKV since it apparently only checks for this flag and not for size...

Other means such as?
