I didn’t have this issue with the last released flatpak of Snorca. I am trying to install the 2.2.4 version of Snapmaker Orca, downloaded off the website. The filename says its Snapmaker_Orca-Linux-flatpak_V2.2.4_x86_64_Beta.flatpak. But when I install it, the installed version in Fedora Software is 2.2.1. And when I start it, the window comes up but then crashes immediately. I think the wrong version of the package got uploaded to the website.
Experiencing same thing here on Nobara 43 (Fedora-based). The appimage works, but I’d rather install it as flatpak.
I have yet to get it to work on Fedora 42 or Fedora 43 (crashes in various ways, sometimes complains abouit the install). I’m doing OK with vanilla Orca, but it’s a bit frustrating.
This has also been posted as an Issue in the Github repo [0]. Is anyone from Snapmaker looking into this? As a new user to Snapmaker the primary issue I currently see is the quality of the software and am concerned that this is a rather big oversight by the company.

So, I was able to build from source on Fedora and it works just fine, I just needed to get the right dependencies. Which means there is no bug that prevents this from working. Which means that the issue is that someone uploaded a broken build. This should be an easy fix, just rebuild latest source and update the download.
For me the same problem. As a workaround i downloaded the 2.2.1 version from github. And that works! 
Better a point release before and a working app. Than the latest (not so) greatest.
I’ll ask the software colleagues to self-check.
The latest version has fixed this issue.
No it has not. Go to the SnapMaker Orca download page, download Snapmaker_Orca-Linux-flatpak_V2.2.4_x86_64_Beta.flatpak and try to install it. The version that gets installed is not 2.2.4, its listed in the flatpak info as 2.2.1. And it crashes on startup.
This may be fixed in the latest source code, but the build that is on the website is not what it says it is.
Got it, I’ll have them download and install to confirm.
This requires confirming the user’s GTK and NVIDIA driver issues. I’ve seen related reports before. Suggest the user downgrade to GTK 4.7, then force-launch the program using the following command:
flatpak run
--env=GDK_BACKEND=x11
--env=QT_QPA_PLATFORM=xcb
--env=__GLX_VENDOR_LIBRARY_NAME=nvidia
--env=WEBKIT_DISABLE_DMABUF_RENDERER=1
--env=MESA_LOADER_DRIVER_OVERRIDE=zink io.github.Snapmaker.Snapmaker_Orca
No, this isn’t an acceptable solution at all. First of all, gtk 4.7 is VERY old, you can’t downgrade a recent installation of fedora to that. Fedora 43 comes with gtk 4.20 by default. Second, your command you suggest is forcing it to run on X11. Recent versions of fedora don’t support X11 anymore, they’re pure Wayland. Third, you’re suggesting I force nvidia, but I’m running on an AMD gpu and I’m still seeing this.
On top of all of that, this doesn’t address that the flatpak on your website is not actually the version advertised. Install it, even though the file says v2.2.4, what gets installed is v2.2.1.
Finally, I’ve shown this is fixed by building from source. You very clearly have a bad build on the download page.
Although I don’t know much about this part, I will pass your feedback on to them.
I haven’t been able to run Snapmaker Orca on Fedora for a long time now.
The state of it is terrible.
I will push them again tomorrow to come up with a good solution.
