Compilation error: exit status 1

I have updated Arduino SAMD Boards (32-bits ARM Cortex-M0+) but it still does not work

That line, wherever it is in your code, is nonsense. I don't know what you intended for it to do, but it is complete nonsense.

Since you didn't post any of your code I will assume that you don't want any help fixing the problem.

its in the library or something i dont know whats wrong

why do you have WiFiNINA files copied into esp32 WiFi library and what has the SAMD core to do with this?

@UMm
Please apply autoformatting to the code (Ctrl-T in IDE) and insert it to the forum again, using the code tags this time.
It will help you to understand that many parts of the code are outside any functions and procedures, what is illegal for C/C++ language. In general, the code looks like a mess of unconnected pieces, it is not a surprise that the code is not compile.

I saw this post

That post is about a completely different type of board. Are you using the MKR Wifi 1010 or an ESP32?

ESP32 board

Please return and edit your post, inserting the code using code tags.
