Cris, let's try this reproduce step-by-step.
First, download the latest Early Access build:
https://github.com/goldendict/goldendic ... or-WindowsExtract it somewhere, and create a new directory
portable, inside the just extracted
GoldenDict folder. That way, you'll be using GoldenDict in portable mode and all its configuration will reside inside that
portable folder.
Copy a couple of your dictionaries into
content folder (it is also located inside
Goldendict folder).
Start this version of GoldenDict, can you reproduce the crash in such configuration?
