Had the same thing happen to me before. Mid race too, cost me a DNF! Got home and found broken pieces of that rod preventing the clutch lever from fully releasing. Bike at the time was '14 250 SX.

There were 2 pieces in against the circlip.  Just got done testing it, 90 degrees and 99% humidity but it worked flawless even after 3 motos20230727 184503.jpg?VersionId=WKW6glyIzVDcq35D

I have a picture of one of those broken in half from my 05 CR250. Glad you got it sorted out.
