#84400 Hi,
I am getting the below error and getting the same error in all programs even though the examples also. Earlier Arduino IDE was not throwing an error like this.
C:\Users\sm00342631\AppData\Local\Arduino15\packages\esp8266\tools\xtensa-lx106-elf-gcc\2.5.0-3-20ed2b9/bin/xtensa-lx106-elf-ar: unable to rename 'core\core.a'; reason: File exists

exit status 1
Error compiling for board Generic ESP8266 Module.
Kindly extend your support to resolve the error.
Much appreciate your kind support.
Thanks in advance.
