How do I fix this error?

Unity Engine
1

In the console there is an error titled

The .meta file Packages/com.unity.timeline/Editor/StyleSheets/Images/Shared/TimelineWarning.png.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

I have tried deleting the packages but they immediately come back before I re import them
Any help would be appreciated

Hey there,

Can you try deleting that meta file and then reopen Unity? It should auto generate one that works…

Hi All, I have a similar problem and could not solve it with the ideas above. I need help.

My problem is the following: I cannot install XR Plugin management, I got many(55/148) of these errors:"

The .meta file Packages/https://com.unity.xr.management/…/Unity.XR.TestSupport… 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"

What I’m done so far (checked many forum posts):

  • tried to install XRPM from the project settings page and from the package manager too
  • tried to delete meta files, bulk, and one by one
  • added full access to the PackageCache folder
  • checked firewall rules
  • deleted the whole Library folder (at every try)
  • deleted the XR loader assets (when I somehow got there)
  • deleted the package-lock json
  • tried the “Help/Reset packages to defaults” menu in Editor

I started with a fresh new VR template:

  • Win11
  • Unity 2021.3.8f1
  • XR Plugin Management 4.2.1

I’m totally lost. Please help.

Thank you in advance!

[SOLVED]
Based on the log file documentation below, I’ve found another Cache folder with npm and packages folders inside of it.
I deleted these folders and now it’s working nicely! (I also deleted the project’s Library folder)

Unity - Manual: Log files (unity3d.com)
my folder was here: c:\Users{myusername}\AppData\Local\Unity\cache

Best, T
