[SOLVED] Blender freezes on Preferences/Save [GNOME 49]

After upgrading from GNOME 48 to GNOME 49 (not sure if it is related), Blender started freezing under specific conditions.

What works
I can fully use Blender:
scale objects, edit meshes, sculpt
real-time rendering with Cycles
rendering single frames and animations

The problem
Blender hangs (completely freezes) whenever I try to:
open Preferences
save a file (when the file dialog window should appear)

What I tried
Completely removed Blender:
sudo pacman -Rns blender
rm -rf ~/.config/blender
rm -rf ~/.cache/blender
rm -rf ~/.local/share/blender

Installed Blender from different sources:
pacman -S blender
yay -S blender
Flathub (Flatpak)
official binary from blender.org

Updated NVIDIA drivers to the latest available in Arch
Installed all GNOME dependencies (to rule out missing packages)

System info:
https://ibb.co/TqcSFhCr

Demonstration:
https://youtu.be/noIgC0cxSWg

The behavior is the same in all cases.
Does anyone have an idea how to debug or fix this issue?

Update: I also tried running Blender with GTK_USE_PORTAL=0 to bypass xdg-desktop-portal, but the problem persists. Preferences and Save File dialogs still freeze completely.

Having this same issue on GNOME 49. Previously blender worked fine on GNOME 48. Also appears to happen when selecting Help > Save System Info.

Tested on:
Flathub (Flatpak)
pacman -S blender

Tested on AMD Ryzen™ 7 7730U with Radeon™ Graphics

All other functionality seems to be fine.

On Reddit, they say this bug has been fixed in version 49.0.2. You just need to wait a couple of days and it will resolve itself, or you can install the unstable version.

Brilliant, thank you!

Temporary solution: it may sound strange, but you can bypass the freeze by resizing the window, for example using the Win + Up / Super + middle mouse button combination — or whatever it is called on your system.

Another temporary solution is to force the blender X11 backend und run via XWayland:

WAYLAND_DISPLAY="" blender

Just had to use this solution to deal with a problem similar to what's described in this thread. Every time I tried to import an STL, I'd get a full lockup and a grey block instead of a file chooser. With this fix, it works fine.

Under Wayland, if you switch to the Vulkan backend, this issue is resolved (at least on AMDGPU). But the preferences window does not have the title bar, so you have to close it with ALT+F4. Luckily, the main window has the title bar.
