mixamo crashes whenever I download animation

generally mixamo works properly: I can upload characters, search for animations and choose them, and they will be correctly shown on my model, but when I try to download the animation, mixamo crashes, like there is an internet issue, but as I checked, my internet seems to be ok. I also checked if the windows firewall is blocking my browser and it's not. Tried different browsers - didn't work either. But for some reason my friend can download the same animations using the same models as I, although we do everything identically.
