Texture "Read/Write Enabled" checkbox keeps resetting

[JaredHays]

I have a bunch of textures I want to flag as readable, but every time I check the “Read/Write Enabled” box and hit Apply, Unity resets the texture type from Advanced to Sprite, and if I change it back to Advanced the checkbox is empty. The meta file confirms that isReadable is not set. I tried setting isReadable directly in the importer settings during a custom import process, but that also didn’t work. I’m pretty baffled at this point; any help would be appreciated.

Where is your project folder located and what OS do u use? i had a similar issue when my projects were in an administation folder on windows moving them outside of this folder fixed it, Not entirely sure if this is the case for you but thought it worth mentioning.
