Compile error with SAMD51

I get the following error trying to compile a code on platformio on SAMD51 itsybitsy m4.

Someone get this error ?

To fix this problem. I had to change the line 89 of piomisc.py. From with open(tmp_path, "w") as fp: to with open(tmp_path, "w", encoding="utf-8") as fp:.

This was fixed in the latest PIO Core. Please re-test with opening PlatformIO IDE Terminal and typing

pio upgrade --dev

Does it work now?
