Comment:

 The error I see in the log is:

 }}}

 So, bmon has defined something (`__unused__`) that interfered with the
 system headers.

 No user software is allowed to define identifiers whose names containing
 double underscores. Those names are reserved for use by the implementation
 (meaning: the compiler and system headers).

 This is a bmon bug, already reported to them here:
 https://github.com/tgraf/bmon/issues/89

 Duplicate of #62820.
