Image cannot be decoded depending on build mode

[dmhk_4ss]

The Image can't decode with some build mode.
Only build mode "Debug" can decode correctly.
It is very strange.
Does anyone know how can I resolve this issue ?

[Build mode result]

• Debug: OK
• Minimum size release: NG
• Release: NG
• Release with Debug Information: NG

Sounds like the jpeg plug-in is only available as debug version.
Does your Qt installation have qjpeg.dll file?
Do you start your app from QtCreator or do you deploy it?

qjpeg.dll

Thank you for your reply.
I found "qjpeg.dll" in the "C:\Qt\Tools\QtCreator\bin\plugins\imageformats" and "C:\Qt\5.13.0\msvc2017\plugins\imageformats"

Do you start your app from QtCreator or do you deploy it?

I started my app from QtCreator.

Thanks.
