Alignment Error

Error during alignment. We have a georeferenced lidar dataset positioned in prior poses on “exact, locked and in 32N coordinates” and a photographic dataset positioned in prior poses on unkdown. Suddenly it tells me that there is an alignment error with the following message: “Aligning Images. Invalid or corrupted input data. Image rigs and laser scans with the prior set to ‘Exact’ mode must be all aligned in a single run. Incremental adding is not supported.”
No additional photos or data have been added, and it does not allow either partial or complete alignment of the data. How can I resolve this problem?
