We don't have a crash when opening release-2021.3 with unity 2020.3.3f1
Please post more information on what hardware, OS, GPU and installation of Unity you have.
Do not use master it is not stable. Did you open simulator release with unity 2020.3.19? If so you may have broken assets. Unity is not backwards compatible.

Are you running this on a remote machine? Can you open a blank project?

[EricBoiseLGSVL]

Do you have mesa drivers installed?

[EricBoiseLGSVL]

Do you have a player log from the editor to see why Unity Editor is crashing?

Do you have mesa drivers installed?

Do you mean vulkan?
Yes, I have use sudo apt-get install libvulkan1

[yumianhuli2]

Do you have a player log from the editor to see why Unity Editor is crashing?
Player.log is my log
Thank you!

[EricBoiseLGSVL]

I don't see anything in the log that helps. Did you delete the old assets in the appdata folder since you are updating to a new version?

The first time an error is reported, the second time can be entered, but the box containing the Build button does not show any assets

[EricBoiseLGSVL]

Do you have asset repos cloned to the Assets/External/ folders?

[yumianhuli2]

Do you have asset repos cloned to the Assets/External/ folders?

1、Do you mean that it doesn't matter if you get an error the first time, but you can finally enter the editor ？
2、Ok, I've read the chapter on Building Assets.All Assets can be downloaded in the https://content.lgsvlsimulator.com/maps, then I need to download to the Simulator which map/Assets/External/subfolder?

[EricBoiseLGSVL]

1. Yes, as long as there are no errors when you have the editor open. It often take Unity Editor a few restarts to fully update.
2. No, these links state that they are for version 2020.06. Github has all the public repos to clone, e.g. Assets/External/Environments/RepoName or Assets/External/Vehicles/RepoName
3. Be sure to enable git lfs when cloning and make sure you are on the correct branch/tags on those repos as well as simulator core.

Hi. I want to run LGSVL simulator by remote machine. And I found the question is that LGSVL-simulator can be running in my server host Ubuntu but can not be started by Xrdp Remote Desktop. And I use gdb ./simulator to catch errors which shows that the libmonobdwgc-2.0.so may have some problems to be imported.
Needless to say, I really need your help! Thanks.

Are you getting a playerlog to see what the errors are?
