Help with finding the reason for a non-working code ESP-WROOM-32

[brightproject]

My project compiles, flashes and works fine with version 3.5.0.
As soon as I change the version to 4.0.0 or 5.0.0 or 6.8.1

Processing stabilo-pcb (platform: espressif32@^4.3.0; board: esp32dev; framework: arduino)----------------------------------------------
Verbose mode can be enabled via -v, --verbose option
CONFIGURATION: https://docs.platformio.org/page/boards/espressif32/esp32dev.html
PLATFORM: Espressif 32 (4.4.0) > Espressif ESP32 Dev Module

• tool-mkspiffs @ 2.230.0 (2.30) - toolchain-xtensa-esp32 @ 8.4.0+2021r2-patch3

The output to the serial port is like this:

13:02:59.893 > [ 4][V][WiFiServer.h:42] WiFiServer(): WiFiServer::WiFiServer(port=80, ...)

13:02:59.924 > [ 32][D][esp32-hal-cpu.c:244] setCpuFrequencyMhz(): PLL: 480 / 2 = 240 Mhz, APB: 80000000 Hz

And the code does not work.
I cannot understand the reason for this behavior.
I found that UART2 on pins 16 and 17, and the IP address for connecting to Wi-Fi can affect, but this cannot affect me, and the same code works on 3.5.0, but does not work on versions higher than this.

github issues is not a place for asking individual programming problems

Hi @brightproject, as @Jason2866 correctly pointed out, the issue tracker in this repository is not the right place for project-specific questions. Anyway, versions >3.5.0 switched from Arduino core v1 to Arduino core v2 which had a great number of changes, so I'd recommend checking if your code was not affected.
