The crash now seems to occur because the picocv assembly is not found. This is the error I get:

Right now picoscope 7 crash even with gtk-sharp-3 2.99.3-5

A fix for that issue is inbound in the next update. It's already in the beta channel since a while

Ditto, same issue. Was going to post a comment about it, and saw there were already 8. :)

Hello,

I faced the exact same issue and I also was able to solve it by downgrading gtk-sharp to version 2.99.3-5.

Thanks rc0r for the hint :-)

I tried picoscope7beta yesterday after all my other unsuccessful attempts. Unfortunately, it crashes with the same exception.

On my system gtk-sharp-3 is only used by Picoscope so it might be possible to explicitly specify the last known working gtk-sharp-3 version in the PKGBUILD file of Picoscope to work around the problem until it's fixed upstream. However, this might of course not be the right thing to do for other setups that have dependencies on an up-to-date gtk-sharp-3.

Maybe you can try the picoscope7beta preview version to see if this got addressed already?

Schorsch commented on 2024-07-23 10:33 (UTC)

Thanks for the update, this would have been my first lead as well after comparing package versions between my system and yours, but I couldn't do any testing yet. I guess then it's only a matter of time until it breaks on my system too. I don't think there is much I can do about that on either the GTK-sharp or Picoscope side. I have to hope they figure it out. Maybe once it hits the official Ubuntu version.

Downgrading gtk-sharp-3 from 3.22.2-1 to 2.99.3-5 fixes the issue for me:

sudo pacman -U /var/cache/pacman/pkg/gtk-sharp-3-2.99.3-5-x86_64.pkg.tar.zst

gtk-sharp-3-2.99.3-5 was the last version I had in my package cache. As I did not check any other package versions 2.99.3-5 might not be the last working version.

Thanks for your efforts @Schorsch! I also installed picoscope on my home workstation after updating all Arch packages. Unfortunately, I'm seeing the same error. However on my office workstation Picoscope worked until yesterday before I upgraded. In 1 there is the pacman log of the updated packages. Please note, I had to downgrade linux and nvidia drivers due to an unrelated issue with multiple monitors. The downgrades should not be the cause of the Picoscope crash as I my home setup didn't require any downgrades and Picoscope was crashing still.

As suggested, I started Picoscope from the terminal mono /opt/picoscope/lib/PicoScope.GTK.exe 2>&1 > picoscope.log 2>&1 >> picoscope.log. The logs can be found in 2. These were captured after doing a clean reinstall of both picoscope (+deps) and the libs required to operate the scope I'm using.

Let me know if there's anything else I could try.
