You haven't shown enough information - also the error states GRID 22952 but you have actually located the element 22952 - Not the same thing.
You most likely have a mechanism and/or rigid body movement.
If you want a complete answer I would suggest uploading a BDF/DAT file or show more - ie. you have shown only one side of the beam constrained, if this is true you will have a mechanism and a fatal run - but we cant see any further constraints.
A quick way you can check is using BAILOUT PARAM or run a modal analysis and return the first 6 modes - if these are close to zero you have a constraint issue.
Also, I would use a washer or pad around the holes to provide a better mesh quality.
