For which platform/board did you compile when this error occured?

Hi I am using NodeMCU ESP-12E board
and Arduino IDE 2.0.4-nightly-20221210
I was using arduino-PR-beta1.9-BUILD-116 before but ESP8266WiFi just stopped connecting to wifi.
I am rebuilding my project for Arduino IDE 2.0.4-nightly-20221210 but now Arduino_JSON is not working :(
I tried everything none of the libraries are working for this IDE.

This may be a very special NodeMCU problem, see here. I'd go and ask for help over there.
