Editor freezes when importing large asset from Package Manager

Packman

-

Steps to reproduce:
1. Open a new Unity project
2. Download a big asset set from AssetStore using the Package Manager (i.e. "AllSky - 200+ Sky / Skybox Set")
3. Click Import

Expected result: Package imports without freezing the editor
Actual result: Package imports while freezing the editor and loading bar shows PackageManagerWindow.MouseUp

Note: After each Import click in Package Manager, the Asset pack is being loaded. Once it's loaded, you can select what assets to import. If you quit this window and Import the Asset pack again from the Package Manager, import times are doubling, slowing down the whole computer. (generating garbage?)

Reproducible with:
2020.2.0b10, 2021.1.0a3 (PackageManagerWindows.MouseUp - full time 20 - 600 seconds at random)
2020.1.12f1 (Saving Unsaved Assets - full time 20 - 600 seconds)

Not reproducible with: 2019.4.14f1 (Decompressing - full time 20 seconds)

  1. Resolution Note (2020.1.X):

    `PackageManagerWindow.MouseUp` was a new feature introduced to show ProgressBar when a function or thread is taking too long and it’s not Package Manager specific either. And it will be addressed in the future.

    This is still happening in 2023, 3 years after this post, in 2022.3 LTS. I simply cannot use this version of Unity, which is unfortunate because some of the packages I bought require it. Unity PLEASE FIX THIS IM LOSING MY MIND

    Can verify this exact thing happened to me. Trying to import a large package (6GB), wish I could get to choosing what I actually want to import before the freeze, I only want a portion of it.

    I've got the same problem. It fixes simply after 7-10 minutes of waiting
