Deep search not finding files

I've successfully built Arduino projects using Arduino and Visual Studio IDEs with VisualMicro. I've rebuilt my PC and have the latest VS2019 (Community 16.6.1) and VM (20_05_18_1).

I'm trying to compile an Arduino programme (unchanged from earlier this year when it compiled OK) and get an error:

arduino.h: 27:20: fatal error: stdlib.h: No such file or directory
An error was encountered during the 'Deep Search' library discovery process.

I can manually find the arduino.h and stdlib.h files in folders under:
e\esp8266\2.6.3\cores\esp8266

and

e\esp8266\2.6.3\tools\sdk\libc\xtensa-lx106-elf\include\sys 

respectively.

I'm pulling my hair out trying to work out what's changed and how I can fix this.

Attached is the compiler output with properties and verbose.

Many Thanks,

Mart

Noticed that there was a version mismatch in the ESP8266 libraries. Just refreshed the libraries and copied the v2.6.3 library using the VM board manager. 

Same error - stdlib.h not found - new log file attached.

I can see a stdlib.h in the files I downloaded in MyDocuments but if I look at where VM has put the updated libraries there's no stdlib.h under:

C:\Users\micro\AppData\Local\arduino15\packages\esp8266\hardware\esp8266\2.6.3

I tried deleting the "C:\Users\micro\AppData\Local\arduino15" folder as I'd seen notes elsewhere that had solved a file not found problem for someone else ... but VS couldn't find any ESP8266 boards - it didn't seem to be looking in the MyDocuments esp8266 library with my .ino file.
