Trovo strana questa riga:
C:\arduino-1.8.19\portable\packages\arduino\hardware\avr\1.8.4\cores\arduino\new.cpp:
Forse è normale ma 1.8.4 cosa il core poiché new.cpp è parte del corelib (e come si intuisce implementa new del C++).
Avevi per caso una versione 1.8.4 precedente?
Ciao.
Ho verificato ed è corretto, effetivamente il nome della cartella è quello sia sotto l'unica macchina Win10 che ho sia sotto tutte le macchine macOS.
E' la versione del "core" come indicato anche all'interno del file "platform.txt":
# Arduino AVR Core and platform.
# ------------------------------

name=Arduino AVR Boards
version=1.8.4

Spiace ma non ho più idee a parte portare il pc da un esorcista 
Lo strano è che funziona appena lo apri. Di solito quando una cosa non funziona... non funziona neppure la prima volta
Ultima idea, nella cartella Arduino ide c'è anche un arduino_debug.Exe
ciao nid, ho provato poco fa pure con arduino_debug.exe. neppure quello risolve.
domani provo dall'esorcista.ultima spiaggia. domani passo dal Vaticano e chiedo il tariffario 
ciao Maurotec, ciao gbp01
qualche settimana fa ho installato il compilatore minGW. non lo so ma ho uno strano presentimento. non è che per caso,durante la fase di installazione, abbia impostato qualcosa che impedisce al compilatore di arduino di lavorare normalmente?
... hai idea le decine di compilatori vari che ho io sui miei sistemi ? 
No, è qualche altra cosa, oltre tutto non capisco perché la prima compilazione vada a buon fine e le successsive si blocchino ... è come se non riuscisse più a leggere i pre-compilati che crea nella compilzione precedente ... 
Con calma, nei prossimi giorni, rifacciamo tutto dall'inizio, passo passo ...

Questa è la prima compilazione di un programma "vuoto" (apri l'IDE e compili solo le due funzioni loop() e setup() vuote) sulla mia unica macchina Win 10:

@xiongmao : ... allora:
CANCELLA qualisasi cosa hai di Arduino sul tuo sistema, incluse cartelle temporanee.
Vai nella sezione download del sito e scarica la versione .zip per Windows
in una qualsiasi cartella dove hai le autorizzazioni sia di scrivere che di leggere scompatta lo zip
vai nella cartella "Arduino" che hai appena scompattato e crea la cartella "portable"
metti in esecuzione l'IDE (arduino.exe) e vai nelle impostazioni delle "preferenze". Imposta le preferenze esattamente come ho indicato in QUESTO post
senza fare altro (e senza Arduino collegato) usa il primo bottone in alto dell'IDE per compilare il programma vuoto che ti viene sempre presentato e verifica che la compilazione vada a buon fine (NON usare il secondo bottone che è per caricare il programma compilato su una scheda Arduino).
riprova ancora ad usare il primo bottone in alto del IDE per compilare di nuovo il programma vuoto e verifica che, anche questa seconda volta, vada a buon fine.
STOP ... e facci sapere.
Guglielmo
ciao Guglielmo,
non sapevo neanche cosa fossero i precompilati 
(ed ad essere sincero non l ho ancora capito bene).
quindi ricapitoliamo. dicevi di cancellare tutto quello che di arduino esisteva sul mio pc. l'ho fatto ma rimanevano alcuni file non cancellabili (forse cancellabili solo come amministratore).
ho messo la cartella di arduino dentro al C:\ , ho creato la cartella "portable" dentro la cartella arduino, compilato lo sketch vuoto con solo setup() e loop() ma la seconda volta che l'ho fatto mi ridà lo stesso erroe di sempre:

Error compiling for board Arduino Uno.
... ultima domanda prima di dirti che devi riformattare tutto o cambiare PC ... non è che hai qualche antivirus attivo che ... è un troppo zelante ?
Guglielmo
uso immunet ma sui servizi è impostato ad avvio manuale (quando devo usarlo lo avvio da me dai servizi). c'è il windows defender
Credo che l'unica prova per poterne sapere di più sia di avviare l'ide da terminale DOS, sperando che stampi qualcosa che ci dia più indizi. Ma non saprei cosa deve scrivere nella riga di comando io proprio windows non lo ho.
Ciao.
va bene, adesso provo. faccio qualche ricerca, qualche prova e poi vi faccio sapere. grazie per l'aiuto a tutti.
ciao Guglielmo,
oggi ho scaricato "windows repair" nella lontana speranza di correggere qualcosa. è venuto fuori questo. non so se può aiutare a capire meglio. la foto in basso è un avviso del firewall di windows defender
Anche se autorizzi continua a dare il problema?
ciao DATman,
si, ho autorizzato ma non va comunque. ho spuntato anche la casella "Reti private,ad esempio una rete domestica o aziendale".
niente da fare. Guglielmo (gpb01) mi ha consigliato ,come ultima spiaggia, di riformattare il pc (il pc è fondamentalmente nuovo. non ha neanche un anno di vita ancora). non mi va proprio di riformattarlo. piuttosto non studio più arduino o piuttosto, chiudo e riapro l'IDE ogni volta che devo caricare lo sketch sulla scheda.
.
Problema risolto. sono ritornato alla versione 1.6 dell IDE e tutto funziona regolarmente. non so perchè la nuova versione (1.8.19 - ho provato anche la 2.0 che assomiglia molto a visual studio code) non funziona.a questo punto. forse ha a che vedere con la versione di java
