Hey peeps! I'll describe this the best I can: Since the April 30th Preview Update, I'm having an issue where Libraries exhibit two issues: Two of them are slow to open in a window, when they used to open just normally. For the ones that are customized with locations I added to have easier access to many things I organize in levels, if you happen to click over the library in the navigation pane to open it, you can see contents normally, but if you click over the same place again, I get a "Working on it" prompt and gets stuck there, if I click it again, then the contents appear again, This is intermittent, one click shows nothing, one click shows content. This shouldn't happen. The rest of File Explorer works normally, it's fast to load stuff, Libraries are the ones exhibiting this issue If I reset Libraries to default, they stop behaving strangely. My laptop and second PC (for Mom) work normally, and my laptop has the same customized libraries, but works as usual. It's just my desktop. I tried everything I could think of: Reset file associations to default, cleaning up thumbnails, restoring views for all folders and trying on a fresh local account (It happens there as well). I can't seem to fix this no matter what. Any idea why this may be happening? It started right after updating to this exact update, I've ran dism and sfc commands, and even did an in-place upgrade. System is clean, fast and snappy, it's just... "this". Thanks in advance for any help you can provide peeps. Cheers!
