I tried to install only this file

What do you mean by "only this file"?  goes without saying that you can't cherry pick specific files and install them on top of older versions if that's what you're doing.

Code:

The .meta file Assets/Obi/Scripts/Common/DataStructures/NativeList/ObiNativeMatrix4x4List.cs.meta does not have a valid GUID and its corresponding Asset file will be ignored. If this file is not malformed, please add a GUID, or delete the .meta file and it will be recreated correctly

Meta files are used by Unity to track relationships between files, among other things. Each file is given a unique identifier (GUID). This means you have a .meta file for an older version of this file that hasn't been removed (see: https://docs.unity3d.com/Manual/AssetMetadata.html). Again, make sure you delete older Obi versions before installing Obi 7.

Also worth noting that dealing with project files outside Unity's editor (eg by using Window's file explorer) can and often will cause problems with .meta files as the information about the file stored in the .meta and the actual file become out of sync. If you delete, remove, rename or move files in a project make sure to do so using Unity instead of an external file explorer.

let me know how it goes,

kind regards
