EvilPortal Crashes after connecting

[Dowan35]

Hello, I have a problem on the evil portal, the program is buggy, while the access point is visible, when I connect to it, 2 times on 3 I have this error message:

assert failed: tcp_update_rcv_ann_wnd IDF/components/lwip/lwip/src/core/tcp.c:951 (new_rcv_ann_wnd <= 0xffff)

Waiting for HTML

It seems that there is a stack overflow or something like this ? I'm just using the basic index.html file and fixed the max HTML size on 7000. I have to stop and start the access point to make it works sometimes.
Plus the content of ap.config.txt is sometimes written of the pop up html page intead of changing the name of the ap.

thanks for your help ! :)
