Package Manager bug preventing me from seeing asset store purchases, 2020.1.0f1

TheBreakfast · July 28, 2020, 3:32pm

Hello, I’m receiving a bug whenever I refresh my Package Manager list when viewing Packages: My Assets. The error is a null reference exception. Is this a known issue, and is there a fix? I want to download some of my purchased assets but the Asset Store is no longer accessible in-editor. I’ve included a screenshot. Thank you.

I’m having the same problem

Zarkend · July 30, 2020, 10:47pm

Same here

fbmd · August 21, 2020, 10:55pm

I have the same problem with 2020.1.2f1
How come nobody cares about such a serious issue
This post is now almost a month old!

chrislarabell · August 24, 2020, 11:46pm

Same issue. Not good since I can’t download them from the asset store either.

putragonist · August 26, 2020, 4:55am

same here… Hope it will be fixed soon
Edit: can be fixed with restarting unity… But it’s annoying since the bug still exist…

hridpath · August 26, 2020, 11:08pm

This is really a hinderance to project development. has there been a bug filed?

Skewbald_Mare · August 28, 2020, 9:39pm

Restarting is not working for me… Bug filed

UpQuark · September 15, 2020, 9:12am

Same problem here, just started with 2020.1.0, the tried newest version 2020.1.5f1, same problem, only 1 asset from My Assets is shown.
Encountered the same NullReferenceException: Object reference not set to an instance of an object problem.
This makes any 2020 version unusable.

Astha666 · October 8, 2020, 5:32pm

Lol same here, with 2020.1.6f. It’s almost 3 months since the problem occured…
Has someone a solution for this problem?

zemeryj · October 9, 2020, 1:12am

Jesus christ its been 3 months this is literally stopping any and all progress in game dev. Guess I’ll move to Unreal Engine or something cause I can’t work here. Even if I get past this, get another issue thats been reported since 2007 pls fix unity.

Why no response?
It’s critical !

timothy92 · October 17, 2020, 10:32am

I’m having this issue too, really frustrating not being able to import assets I paid for

Same problem!

expandrew · October 20, 2020, 11:06am

I was also experiencing this issue with Unity Version 2020.1.9.f1. I also have TONS of assets in my saved asset library, as I got to collecting free assets for a while there. A lot of those assets had since deprecated.

A workaround that I have so far found helpful was to go through all of my assets in my Asset Library on the Asset Store website and find all of the deprecated ones and Hide them. Then boot up Unity and log back into the hub again and check the Package Manager and I seem to more readily and easily be able to load my assets.

Hope this helps.

Having the same problem here. Unity 2020.1.4f1

HP1 · October 28, 2020, 8:30pm

Problem still exists with Unity 2020.1.11f1
Hiding the deprecated packages doesn’t help.
