Muse Sampler Library is stuck at version 0.100.7

I tried adding a sustain articulation to the Muse Guitars (both volumes) obtained through MuseHub in MuseScore Studio version 4.4.4, but the notes play staccato during playback and ignore the annotations.

I'm running MuseScore and MuseHub on Windows 11.

I've checked the Diagnostics tab in the toolbar of MuseScore, and clicked on "Muse Sampler" to see which version the Muse sampler was on, since I'd read before that that was the source of the issue for many other people, but not once did I ever find an actual solution to the problem. It was just stuck on version 0.100.7, while I was reading that people had a version all the way up to 0.6 and were able to just suddenly make it update with no explanation.

I've done a completely clean reinstall of both MuseScore Studio and MuseHub, as well as every single sound group in the MuseHub library. I restarted my PC before and after starting up MuseHub after a fresh reinstall. I restarted before and after reinstalling MuseScore. I restarted before and after again after re-downloading every single sound group. Then I repeated the whole process and restarted before and after doing so. MuseScore is still saying that the muse sampler library is at version 0.100.7, even with all these steps. I've done this whole process about four times, with the same results every single time.

I checked to see if I had the MuseSamplerCoreLib file in my System32 folder, and it wasn't there, even after each and every reinstall that I did.

I enabled auto updates for MuseScore, MuseHub, and MuseSounds in the MuseHub app, then repeated the reinstall process I mentioned. Still nothing.

I've looked for hours now trying to see if someone had a different solution, but all I see are dead threads and vague, unhelpful answers barely pertaining to the "fixes" I mentioned above.
