The only successful way to put everything into my Kobo at the moment is to copy/paste my Calibre library folder into the Kobo folder, but without the covers/metadata I modified with Calibre.
Is it a Kobo firmware/Calibre software update issue? Am I the only one having this problem?
This seems to contradict the later conversion errors. If you are copying the files from the calibre library directories to the device, they should have errors like the conversion is seeing. Or have you previously done epub-to-epub conversions and now have ORIGINAL_EPUB files as well? If so, a new conversion will process these. If they have somehow become corrupt, that would explain the conversion errors.

And just to confirm some things about how this all works...

When you send books from calibre to the device, the top format in the list of supported formats will be chosen and sent. This will be updated with the latest metadata and cover from the calibre library. Manually copying the book means that they get there unchanged.

After sending books to the Kobo device, when it is disconnected from the PC, it should display a black "processing" screen. This has a progress bar and percent complete as it processes all the new books into the devices library (reads metadata and ToC from the book and puts it into a database).

If the processing screen doesn't get displayed, it should mean there were no new books added to the device. This could mean the wrong formats were sent (wrong extension), or they were put into a place that the device doesn't look in (directory starting with a dot).

Sometimes a book can cause a problem with the processing. This happened a lot in the past but not as often now (on average books are better and the firmware has improved). If there is a problem, the processing usually stops and all books after the problem one are skipped. Whether earlier books are added, I'm not sure. In older firmware, they definitely weren't but the recent firmware has changed something in this and they might be.

My guess is that if the books in the calibre library are corrupted, then sending them to the device might work, but I would have expected an error from calibre when it attempted to update the metadata. If there wasn't an error, then when the books were processed by the device, it probably means the processing failed for the first book and all others were skipped. At this point, I would recommend removing all the books and finding one that is definitely OK (maybe grab one from the MR library). Then sideload and see if it appears in the devices library. If it does, then you need to find new copies of the corrupt books. If it doesn't, we'll have to think about what is happening.
