Hi @saryasom, thanks for reporting. I will investigate this issue. I think it relates to the new feature in 1.6. It would be very helpful if you could provide step-by-step instructions to reproduce this issue.

Hi. I facing the same issue when set 20 backgrounds(as an example) and set the change background interval to 10 seconds and it crashes all the time it changes the background after the first interval time.
I use UE5.6.1 built from sources.

@frostweep Currently, I recommend setting the Background Interval to 0.0 to disable updating the background until I find a solution to fix the conflict with ZenLoader

[frostweep]

Yeah, that's what I did. I think there need to move loading of image outside of OnPaint somewhere in GameThread to fix that but I didn't find a final solution yet

Hi @saryasom @frostweep, please update to the latest version and enable the Background Update option to see if the crash persists. Note that you need to add the loading images folder to AdditionalAssetDirectoriesToCook. Please read more in IMPORTANT NOTE
