Hello

I use a V5.1 Release Path of the ESP-IDF

I put only the Core1 the Wifi handler only, my application runnning on the Core 0. Sometimes work flawlessly 1+ times and when this happens random error can cause.
I see this error:

I run the code on my own hardware. I cannot attach any JTAG ....

Where I made a mistake? Is there any advice?
Code can be seens here:

Any help pls???

I could cause similars in the CORE 1 if I move the Wifi from th SDKconfig to the CORE1 ....

Is this my fault or feature of APSTA or? I tried the last 2 weeks tons of setp of the sdkconfig, adding more stack , removing unnecessary components --> no change I still casn kill it around AP connection time or the httpd server connection / html file download + WS connection time randomly.....
