Select Dropdown Click Crash - CEF EXCEPTION_ACCESS_VIOLATION

[mangoplane]

Hi.

First of all, a massive thanks for your work on this super useful project so far. Unfortunately I get this error when I try clicking on a drop down select on https://webauthn.me/debugger, causing the entire game engine to crash (at the very moment I click the dropdown). Do you have any ideas why this is, judging by the error output? Seems to be some sort of memory access error, occurring within 90.0.4430.212_windows64. To that end I wonder if we update CEF, whether that would automatically fix the error.

Thanks!

I wonder, would it be difficult to update CEF to latest and do a PR to https://github.com/getnamo/BluBrowser?

Which engine/plugin version are you using?

Which engine/plugin version are you using?

v4.6.0 for UE 5.1

[getnamo]

Do you get the same error on an older build?

E.g. https://github.com/getnamo/BLUI-Unreal/releases/tag/v4.5.0?

Curious if directly related to the CEF update or if it's something that's been there before

Hey, I'll be sure to try this out soon. Just working through another issue now, which is also present in the native Unreal browser.

I can confirm the error isn't present in the native Unreal Engine browser. Just Blui.
