Object reference not set to an instance of an object

During compilation, after update Visual Micro and Arduino IDE, appeared strange error like "Object reference not set to an instance of an object".
And even when I try to compile very simple project "Blink", I got following messages:

Compiling debug version of 'Blink' for 'Arduino/Genuino Mega w/ ATmega2560 (Mega 2560)'
     Preprocess: "{runtime.tools.avr-gcc.path}\bin\avr-g++" -c -g -Os -w -std=gnu++11 -fpermissive -fno-exceptions -ffunction-sections -fdata-sections -fno-threadsafe-statics -flto -w -x c++ -E -CC -mmcu=atmega2560 -DF_CPU=16000000L -DARDUINO=106011 -DARDUINO_AVR_MEGA2560 -DARDUINO_ARCH_AVR -I"C:\Program Files (x86)\Arduino\hardware\arduino\avr\cores\arduino" -I"C:\Program Files (x86)\Arduino\hardware\arduino\avr\variants\mega" "C:\Users\F\AppData\Local\Temp\VMicroBuilds\Blink\mega_atmega2560\Blink.cpp" -o "nul"
   Object reference not set to an instance of an object


     An error was encountered during the 'Deep Search' discovery process.
     Either resolve the error or switch off the 'Deep Search Includes' option.
     Tip: When deep search is switched off, headers must be #included in the [project_name.ino] for all required libraries (for example: #include <SPI.h>)
     Tip: Deep search must be off if the project source contains links/shortcuts to code outside of the project structure. The source will have been #included using a relative path preceeded by ..\ (for example: #include "..\..\foo\foo.h")

I tried to switch off Deep Search, but after this got Error compiling core:

Compiling debug version of 'Blink' for 'Arduino/Genuino Mega w/ ATmega2560 (Mega 2560)'
     Process: "{runtime.tools.avr-gcc.path}\bin\avr-gcc" -c -g -x assembler-with-cpp -flto -mmcu=atmega2560 -DF_CPU=16000000L -DARDUINO=106011 -DARDUINO_AVR_MEGA2560 -DARDUINO_ARCH_AVR -I"C:\Program Files (x86)\Arduino\hardware\arduino\avr\cores\arduino" -I"C:\Program Files (x86)\Arduino\hardware\arduino\avr\variants\mega" "C:\Program Files (x86)\Arduino\hardware\arduino\avr\cores\arduino\wiring_pulse.S" -o lse.S.o"  
Error compiling core

What I did wrong?
Thanks.

I'm having this same error and restarting the IDE or hitting rescan isn't fixing it for me.

Is there a specific version of the Arduino IDE I should have downloaded?

No idea what I did with settings and updating libraries but eventually it started compiling.

I found the issue which could sometimes happen after visual micro deleted the temporary build folder prior to re-build.

The latest release prevents the issue from happening and also includes a number of important fixes to "library search/discovery".
