Full logs

• rustup 1.27.1 (54dd3d00f 2024-04-24)
• cargo 1.83.0-nightly (c1fa840a8 2024-08-29)
• rustc 1.83.0-nightly (12b26c13f 2024-09-07)
• espup 0.12.2

Also seen #319 with the same error, which should be already fixed.
BTW I didn't found a clang.exe file in C:\Users\Tnze\.rustup\toolchains\esp\xtensa-esp32-elf-clang\esp-clang\bin

This problem is not directly related to the hal but to how the xtensa toolchain gets installed. The issue is already tracked in espup here
