Good morning,
I am working on a firmware for a custom board featuring an NRF52833 + an NRF21540 FEM; I am creating both a peripheral and a central device.
The problem I ran into several times now, is that at a given point, without any evident reason, my code stops compiling and I get a bunch of
errors that are difficult to understand and which are reported below.

The issue appears on code that worked perfectly fine; in the case above I just added 1 line of code, and the error arose.
Of course, I tried removing the newly added line of code, but got the same error.
As I already did in the past, I removed the project and got a fresh copy from the git repository storing functional code; still the same error.
I tried reboot of the computer, still error.
Every time I ran into this problem, I spend a ridiculous amount of time trying random things, until in the end, for an unknown reason, the
code compiles again.
Is anyone able to understand what happens here, and what is the solution to fix the problem?
Thanks in advance,
Lorenzo
