Runtime crash with provided examples

[alka79]

Hello,
To discover the library, I tried some provided examples with a ESP32-C3 (Super Mini) and a ESP32 WROOM (D1 mini)

I started with simpleServer.ino : compiles but crashes at runtime during setup it seems.
Then tried simpleServerCaptive.ino : it works fine. I could enter my wifi credentials on the /setup page.
Then tried withWebSocket.ino : crash at runtime same as simpleServer

crash with sampleserver.ino or withWebSocket.ino

This is "simpleServerCaptive.ino" example.
Open /setup page to configure optional parameters.
Open /edit page to view, edit or upload example or your custom webserver source files.

I use board ESP32 version 2.0.17 and latest versions of all libs.

Obviously there are differences in each example. Are there any particular recommendation and/or requirements ?
