I ran into this as well, but I found no other reports of the issue so I thought it was something with my configuration.
It looked like the issue was two missing libraries that were indirectly referenced from the git repository. I fixed it by copying the missing libraries from the git repositories: Seeed nrf52 git repository
I think these were the two libraries I copied over:
- Adafruit_TinyUSB_Arduino
- Adafruit_nRFCrypto
Those libs are links in the git repository and the destination directories are empty: C:\Users\XXXX\AppData\Local\Arduino15\packages\Seeeduino\hardware\nrf52\1.1.3\libraries
