The OBR rules include one that says their forecasts must be based on stated government policy at the time of the forecast. While other forecasters can anticipate changes in government policy, the OBR can not, even when the changes are widely known. I suspect that changes in policy account for much of the discrepancy.
The Liz Truss "mini budget" was anything but mini and was described as "mini" specifically to avoid the OBR from publishing an analysis of its impact on government finances. The OBR have a legal duty to publish their assesment of the impact of budgets so this was a way around that. The "mini budget" and its aftermath didn't make the previous OBR forecast look good.
Incidentally, Truss was so determined not to release an analysis of the mini budget that she sacked Tom Scholar, the Treasury Permanent Secretary, for "old fashioned thinking". We now know that "old fashioned thinking" was insisting that the markets would be expecting an analysis and that they would fear the worst if one wasn't published.
