Unity asset bundle - cannot find the file path

Hi.

Does anyone know why I’m getting:

Opening file (FolderPath)/tsubaki.meta the system cannot find the file path specified erorr when building asset bundles? Could it be happening because I have two unity instances open building asset bundles?

Currently I have a server which builds a 3d asset and builds it as asset bundles, which is sent to the client and opened there.

Now, since I’m serving users in iOS and Android I have to build asset bundles for each platform. To reduce time spent on switching build targets, I have two unity editor instances open which will build asset bundles for each platform and send it to our server database.

Normally, the system works fine. However, every few hours (I don’t know the exact interval for the event), unity shows the error screen with this message.

Does anyone know why this error might be happening?

Thanks.

Yes, if by that you mean you have somehow managed to open the same project with two editor instances. Normally Unity won’t allow this (“project already opened”).

If these two editor instances have two different projects opened, but some of the assets are shared ie via symlinks/hardlinks or “from disk” packages imported from the same location, then this may also cause issues.

Otherwise, check if the file actually exists and if it is, whether anything is preventing access to it. Always recommended to exclude Unity projects from on-demand virus scans.
