Starting today some directorys' access permissions go haywire on my laptop meaning I can longer access them. (That is, a directory is created, available and usable for a while, before something goes wrong.)
For a problematic directory, when I view its properties and go to the Security tab, I see
(i) You must have Read permissions to view the properties of this object.
When I click on Advanced, I see:
Owner: Unable to display current owner.
Clicking on Change (as administrator) fails with:
(i) You do not have permission to view or edit this object's permission settings.
Clicking on Continue from the Advanced dialog has the same result.
If I start a
cmd shell as Administrator, I cannot
cd into the directory. Nor can I delete it.
Initially, the directories in question were created when coding using the IntelliJ IDE. That is, they are created by IntelliJ as sub-directories of the project root, typically several levels down. Shutting down the IDE does not help. Sunsequently the issue arose in a directory that was part of an un-zipped file completely unrelated to IntelliJ. So it seems it can occur anywhere.
A reboot has fixed occurrences so far, but this is getting really annoying. That is, after a reboot I can delete the problematic directory and get on with my work for a while. Then the issue will crop up again, typically with a different directory. As time went by, the period between occurrences decreased to the point I was rebooting every few minutes.
PS: As noted above, this problem has only shown up today. First thing this morning, a large Windows 10 update was applied. I'm not sure if this is related but the timing is suspicious. That is, the problem has only occurred since the update.
