It would be helpful if you could provide a minimal reproduction starting
from "emacs -q".
My immediate suspicion is that flymake-mode is (somehow) enabled in your
C files while flymake-diagnostic-functions is set to contain flymake-cc,
which causes flymake-cc to start up a background process. Then,
flymake-mode is enabled again by eglot--managed-mode, which causes
flymake--state to be cleared, so when flymake-cc tries to report
diagnostics from that background process through flymake--handle-report,
it fails.
But I can't be sure whether this is due to a bug in Emacs or due to a
bug in your config without a more minimal reproduction.
