Glare effect not showing

hi, i’m a blender beginner user, i’ve followed some tutorials to how get the blurry/glow effect on my project, and i’m currently struggling with the render process. The glare effect doesn’t show up on the render port, but it does show up on the viewport. ( the post-processing settings are checked and everything looks like it’s set right)

This is how its supposed to look like:

Also if anyone has any tips on how rendering in high quality please let me know! I’ve tried switching between different numbers of samples but it still looks very low low quality and very blurry ( low dpi)

Oh by the way, I’m currently using Blender 3.6.0

Hello,
It’s hard to say what the issue could be, since there are many possibilities. Are you using a node setup in the compositor? If so, have you plugged the glare into the composite node? If it is still plugged into the viewer then it wont render the effect. Sorry, if this isn’t at all helpful. I’m not entirely sure what method you’re using.
