not enough calibrated points problem for report generation

hello
i wanna generate quality report after adding the GCPS but it keeps failing, this is the error i get:
[Warning]: Warning w9020: GDAL Error <4> V:/2025_agadir souss massa Amenagement/agadir finale/1_initial/project_data/thumbnails/459_DJI_0444_512.jpg: No such file or directory

[Error]: Error e0900a: Cannot export point cloud in LAS/LAZ format. There are no points.

knowing that the gcps are in fact covering the zone, and exists in the folder in which the error says that there is no such files. also the project is made out of 6 seperated projects for which the initial treatment is done. what should i do in order to get the report project so i can generate the cloud points.
