Hi,
I have a project from v2 (2.4.2) that works fine without any trouble. I wanted to continue working on it in v3 (3.2.10) but when I try to open the project file v3 crashes and gives me the following error message:
INFO : Handling urls … (MainWindow._processDroppedItems:1524)

AttributeError: ‘NoneType’ object has no attribute ‘lower’
I already looked through all files within the project to see if there was anything unusual but that does not seem to be the case. Is there any suggestion what could cause this problem?
thank you very much,
