Crayfish plugin crashes QGIS. QGIS 3.22.4-Białowieża

[simonweppe]

Hi there,

I am trying to install the crayfish plugin in qgis 3.22.4, but running into issues. I can find the plugin in the catalog, but when I click on install it will crash qgis.

When I restart qgis, the plugin is here but disabled. I can "re-install" and it say it's successful.

After a restart, if I tick the Crayfish box in plugin list on the left, qgis crashes again.

I can't see any error messages so I'm a bit lost !

I installed qgis using the steps here (Section Debian/Ubuntu Quickstart)

Install info below, happy to provide more details. Note I did have to install pyqtgraph first as suggested in here to move past a first error.

I finally got to an error message :

I did try to play with that pyqtgraph versions...but ended breaking my install and re-install a fresh qgis version, so stopped there :)

Hope you can help @wonder-sk
