At some point a few weeks ago, when I'm opening a new explorer or even a new tab, explorer takes ages to become fully operational. In the meantime it looks like this:
I can type a path, browse, etc.. but my shortcuts (on the left) aren't available for at least one minute. After that, they appear. But if I open another tab, here it goes again.
Also, all file explorers don't show the shortcuts ever, only the drives.
Of course, killing explorer, rebooting, does nothing. It's a permanent thing.
I've googled for this error but never really could find the exact error I have. Most people get permanent slowdowns, that's not my case: file navigation is fast enough.
note that I have only a SSD drive, no mechanical slow HDD or such.
