When i use my gaming PC to open a test project by using unity 2020.3.10,i can import all my unitypackage files,but when i use my new working PC to open a test project(same default setting) by use same version of unity(2020.3.10),all my unitypackage file can not be import.

I try to use all english path,all english file name,it’s not working,but i still can imoprt those unitypackage file in my gaming PC even they share the same path name…

It always tell me like this:
Failed to import package with error: Couldn’t decompress package
UnityEngine.GUIUtility:processEvent (int,intptr,bool&)

Anyone know how to fix this or something could make this happen?

Here is my situation:
1.My work computer is brand new, with unityHub and Unity installed from scratch.
2.My unitypackage files are fully available on my other computer
3.My unitypackage files are all stored on the same path to the portable hard drive
4.The assetstore unitypackage on my work computer import automatically as normal, but I can’t import all of my own packages.
5.Even if there is a non-Latin alphabet path, my other computer still can import them.

Out of curiosity, how much free space do you have on your default drive on the machine that isn’t importing?

I get this error every other asset from the Unity Asset Store it feels like. It has nothing to do with available disk space for me at least. Sometimes it’s fixed by navigating to where the asset is downloaded, deleting the file and downloading it again, but more often than not I have to use 7zip to open the .unitypackage file, export the file inside it, delete the original package and then add .unitypackage to the end of the exported file. This was a fix I found randomly on Google and it actually works. No idea why or how or what has to go wrong for a fix like that to fix it.
