sudden permission denied error, sneak peek

Hello,
I’ve been working with verge3D for last month. It’s been working great.

But suddenly, for no apparent reason, I can’t sneak peek anymore.
(note: I have checked the folder permissions they are perfect. I can read/write anything to the verge3D folder and subfolders using powershell or explorer, also note that this happens now for any project/App, not just my new one.)

All I get is this:

Traceback (most recent call last):
File “H:\verge3d\addons\verge3d\custom_ui.py”, line 441, in execute
shutil.rmtree(prev_dir)
File “C:\Program Files\Blender Foundation\Blender\2.79\python\lib\shutil.py”, line 494, in rmtree
return _rmtree_unsafe(path, onerror)
File “C:\Program Files\Blender Foundation\Blender\2.79\python\lib\shutil.py”, line 393, in _rmtree_unsafe
onerror(os.rmdir, path, sys.exc_info())
File “C:\Program Files\Blender Foundation\Blender\2.79\python\lib\shutil.py”, line 391, in _rmtree_unsafe
os.rmdir(path)
PermissionError: [WinError 5] Access is denied: ‘H:\\verge3d\\addons\\verge3d\\..\\..\\player\\preview’

I’ve tried everything. Can’t fix it. I’m pretty bummed out that this just happened suddenly for no reason. Hmmm. Tried a bunch of other things, started new app, etc. Still not working.

Any help much appreciated.
