Failed uploading: uploading error: exit status 1
By the way... the errors in the code box are my IDE not uploading code to any clone Nano (microUSB, miniUSB and USB-C), but the same IDE uploads to ATtiny88 MHETLIVE Micronucleous. CH341 removed and installed. AVR boards removed and installed. Windows 11, IDE 2.3.6. All my boards upload with the AppImage 2.3.6 on Linux Mint 22 (most recent LTS).
[EDIT] The problem was all mine. TOOLS >> PROCESSOR >> 328P (I forgot my Nanos are not old bootloader). Ugh.
