This does not happen with all of our packages, but most of them - when I open them in TOAD (126.96.36.199), the “first tab” opens fine, navigator looks good, can refresh without issue - but the second tab (package body) the navigator tab is blank, though the file itself looks fine. I click refresh (in the package body tab), and it crashes (not instantly, spinning wheel of death, Windows 10 Pro, still going after 10 minutes).
Fresh download of the Beta, had just opened it, so options should be default. If there is some specific debug information or anything you’d like, let me know. I opened a bunch, and I can’t find any consistent thing between the files that “work” and “don’t” to distinguish them from each other, it just seems to be random.
