Internal Error: EPERM: operation not permitted, open '...\.yarn\cache\.gitignore'

Hi,

I've been using volta for pnpm and npm for a while now.
I just tried to install yarn and it's just not working.

I get the following error:

Internal Error: EPERM: operation not permitted, open 'D:\...\.yarn\cache\.gitignore'

I tried multiple yarn versions, git bash, windows cmd, with and without admin rights.

My pnpm also broke. So I rebooted.
Now I get this on yarn4:
#1054

Error: @sveltejs/package@patch:@sveltejs/package@npm:1.0.0-next.1#.yarn/patches/@sveltejs-package-npm-1.0.0-next.1-2fd015530b.patch::locator=%40builder.io%2Fmitosis-repo%40workspace%3A.: ENOENT: no such file or directory, open 'D:\...\.yarn\patches\@sveltejs-package-npm-1.0.0-next.1-2fd015530b.patch'

And this on yarn3:

Internal Error: @builder.io/mitosis-repo@workspace:.: This package doesn't seem to be present in your lockfile; run "yarn install" to update the lockfile

I have some more information.
My (company managed) virus scanner seems to block the node.exe because it's in an odd place.
After that happens all yarn process end up failing with EPERM until I reboot.
I'm currently in contact with some people to get this resolved and I'll try again if/when the block is lifted.
