Buttons don't work with post processing Newbie question

I added some lens distortion and what not to my game but after this buttons no longer work. Weirdly when I create a new canvas and throw the button in there it works but if I change that canvas to Camera then the button breaks and going back to overlay the button stays broken. Might just be an issue with Unity but I cannot for the life of me figure this out, and having buttons and UI outside of the Post processing looks janky, but under the main camera all UI elements break entirely.

Has anyone encountered this and if so what did you do to fix it? I saw a megathread I think might be related, but the extent of fixing Unity's render graph is a bit too much for me. If that is the only way then I will concede, but I have to imagine there is a better way to handle this.

I also recognize this lacks alot of details, I am new and not entirely sure what could be helpful here so if anyone has questions to help me better approach this I would be happy to provide whatever!


EDIT: sorry I should mention, I followed this tutorial for the post processing I have in my game: https://www.youtube.com/watch?v=lOyb0\_rFA1A&t=79s

URP build issue with custom shader

Never had any issues with creating custom shaders in Unity 6, by selecting a new shader in the UI. However, I got an URP example from a source for an unlit shader and out worked great in testing on my PC. However, after building and running on an android device, the shader just rendered that darn violet color of dead. Any clues?

In the meantime, I went back to using the standard unlit shader.

💥 I made a retro tank battle game inspired by Pong, Breakout, and old Atari cabinets!

Hey folks!
I'm a solo dev and huge fan of early arcade games from the '70s. I just released a browser-based game called Retro Tank Battle, built as a tribute to Pong, Breakout, Gun Fight, and Tank.

It's a quick, pixel-heavy, ricochet duel with breakable blocks and 1970s-style visuals. No fluff — just pure arcade-style fun.

Let me know if you're interested — I'll drop the link in the comments!

(And if this doesn’t belong here, mods please feel free to remove it.)

Im stuck with no default font in my editor!?!

I have a project ive been working on and i was in the 2022.3.40f1 version of Unity and so i decided to jump forward to the latest recommended version (Unity 6.0 6000.0.47f1), i do this and when my project opened i noticed a lot of UI glitches around the top of the screen, mainly things overlapping, i go and hover my cursor over them and i get flooded with these errors

Unable to find a font file with the specified Family Name [System Normal\] and Style [Regular\]. UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

ive spent the last 2 hours with chatgpt trying to figure out what the problem is and how to fix it but nothing it suggested worked for me, i dont recognise this font as any that i use and ive deleted and updated my manifest.json a bunch and still have no silver lining, pls help me :')
