New Crash With Latest Marketplace Update

[Sikotik13]

Installed the latest update for UE 5.0.2 from the marketplace this morning, and now on opening a material graph, the editor crashes. Short log, at least:

Assertion failed: IsValid() [File:D:\RocketSync\5.0.0-19505902+++UE5+Release-5.0\Working\Engine\Source\Runtime\Core\Public\Templates\SharedPointer.h] [Line: 1074]

This log was on a creating a new material and attempting to open it. The crash happens as soon as the material graph opens.

Not sure how related it might be, but I just had the crash repeat on trying to add a function call from a context menu in a scene component blueprint. Same error log. Since it may or may not matter, for this one, I was trying to use a specific function from a plugin, it didn't do it before with anything else, so it may just be random, will attempt to repeat it, if possible.

[Sikotik13]

Nope, just added that same call, in the same blueprint (just reopened the project and asset post-crash). Worked fine this time. Weird error, but hopefully it helps in some way that the crash can be provoked randomly?

Sorry about this, I believe I have fixed this now. You can download the hotfix here and replace the BlueprintAssist plugin folder (located at Epic Games/UE_5.0/Engine/Plugins/Marketplace/BlueprintAssist).

• 4.26
• 4.27
• 5.00

Let me know if you do encounter this again. This update should be out on the marketplace in a couple of days.

EDIT: Made the files public Update is out on the marketplace

[Sikotik13]

It definitely at least seems fixed for me. Kudos!

[fpwong]

Thanks for reporting this so quickly @Sikotik13. Keeping this issue open for visibility in case others look here for a solution. I will close it once the update is live on the marketplace.

@joergselters you need to do what he said a couple comments above yours

[fpwong]

Update 3.3.1 is out on the marketplace now

[kvick-games]

Still getting this after the marketplace update

[fpwong]

@SGMike Do you remember what caused the crash to happen? Was it on opening the material graph or during some other event?

[kvick-games]

Unfortunately I dont know an exact repro. I was basically just working in UMG widget blueprints and it would crash every 20 minutes or so. I can play around with it some more tomorrow and maybe get an exact reproduction.

[kvick-games]

@fpwong I haven't run into the issue today, I ended up having some issues with my binaries, after cleaning out the binaries and intermediate folders and rebuilding it seems like that might have been my issue locally, sorry about that!

[fpwong]

@SGMike That's great, let me know if you find any other issues
