Audiveris
I recently found an old copy of Audiveris on my system and went and found the newest version on github and managed to get it running without text OCR. For those of you who dont know it it is a MCR or OCR for music. I have tested several PDFs from IMSLP and have been very pleased with the results. It is not perfect in its interpretations but a sheet of A4 music can be translated into MusicXML, input to MuseScore and be checked/corrected in around 15 minutes (YMMV)
Its not the easiest thing to get going (at least on Linux) but its very useful and may help with OpenScore if thats still a thing!

Are you aware that the MuseScore menu selection File > Import PDF... already provides a link to a version of Audiveris?
As regards OpenScore: I have been involved with the OpenScore Lieder Corpus since 2018, and most transcribers seem to prefer manual transcription to optical music recognition (OMR). I have tried the MuseScore Import PDF... option, without much success. But I do use other (commercial) OMR programs on a regular basis and find them very reliable. Example of a score captured with OMR:

Yes I have tried the MuseScore one and it never returned anything for me. I have used older versions of Audiveris < 4.0 with not a lot of success. When they moved to Git-Hub I was unable to get it to build and then a week or so ago I gave it another go and its come on a long way and with little effort I can convert and tidy up a sheet in around 1/4 hr. Given its free I'm quite pleased with that.
