Hi, thanks for the report. I suspect keyboard language and layout might be affecting this.
Do you've non-english layout selected?
Could be related to: #51283, #80795

Are these key presses recognized outside of blender (ex: text editor)?

I use the "US International - PC" layout. Works fine outside of blender. Works fine even in the script editor and if i set the Accent Grave in the key-bindings.

If i search the keybindings for i do find 3D View - View (wm.call_menu_pie)(VIEW3D_MT_view_pie) It is set to and click drag and i can reassign the accent grave key using my keyboard. But it won't work in the 3D View.
If i set the keybinding to e.g. "y" and click drag it works.

@ChAoS_O Could you try creating a new user account on your machine and only fresh install Blender in there, to see if the default macOS and Blender its own settings will give you access to the Accent Grave / Tilde key? For I can use it on an MacBook Air M1 model 2020 running macOS Ventura 13.4.1, giving me the Pie Menu you are missing. International keyboard here (vertical Enter-key) in the MBA and on an external keyboard as well.

@ChAoS_O , thanks for the update. Does view pie menu open in other editors? (ex: timeline)

Could you try creating a new user account on your machine... to see if the default macOS and Blender its own settings

Instead, either delete the config folder or do factory reset: File > Defaults > Load Factory Settings :)

Tried it with default settings. Same problem. After trying default - i set the key again in the bindings, it recognizes the key when binding, but still not working for the pie menu (tested with 3d view and timeline).

@mano-wii , can you verify this on Mac?

In fact there seems to be a bug here.

I analyzed the code and at first wondered why kVK_ANSI_Grave is commented out here:
f1e4903854/intern/ghost/intern/GHOST_SystemCocoa.mm (L259)

But that's not necessarily the problem. It is commented out since the Cocoa system was implemented in Ghost: 3f3c2d0204

And the UCKeyTranslate function is in charge of identifying these keys.

But for some strange reason, UCKeyTranslate is not identifying the key when pressing it. It only identifies when releasing it.

I have the impression that it worked before. Did some driver update break it? Needs investigation...

@mano-wii hi, can we backport your fix to LTS? :)
