Cannot find nimble since espressif32 update a few days ago

Hi,
Before posting I searched for “nimble” but didn’t find anything relevant to the problem I am having.
I accepted an espressif32 update a few days ago. Since then I get this problem "Cannot find “C:\Users\David\.platformio\packages\framework-arduinoespressif32\tools\sdk\include\nimble”.
The build works ok and I can delete the two lines referencing nimble from the json file to temporarily get rid of the reported problems. The json file gets updated each time I start VS code and the problem reports come back.
I’ve checked to see if nimble exists in the location and it doesn’t.
Can anyone tell me how to fix this?
TIA
Dave
