at least on my system, running enmapbox/__main__.py is crashing now:

‌

Process finished with exit code -1073740940 (0xC0000374)

Looks like the crash we observed earlier in the shared screen session, where we tried to use initAll():

from enmapbox import EnMAPBox, initAll
from enmapbox.testing import start_app

qgsApp = start_app()
initAll()
enmapBox = EnMAPBox(None)
#enmapBox.openExampleData()
qgsApp.exec_()

When skipping the initAll(), the Box is starting, but the import/export dialogs aren’t working.

Can you start it from terminal?
Cam you start it from a clean environment (EnMAP Box Repo only, source folders as described in repo docs)? Please list your environment / sys.path

Ok, I think I can reproduce it, and it is not random as I thought:

At this point:

‌

func.name() is “'format_py“, and when evaluating QgsExpression.isFunctionName(func.name()) it chrashes:

Benjamin, does that help? Or shall we have a shared screen debugging session?

[Benjamin Jakimow]

Indeed a very good hint. I restructured the registration of QgsExpressionFunctions, for which Python instances have to be stored (of course) and, in this case, got overwritten.

Works fine now, thanks!
