I created a QGIS project and uploaded it to QFIELD. There, I edited and added new data to the files in the field. Everything was saved correctly. Yesterday, back home,  I reviewed all the added data in Qfield at home. Today, I tried to synchronize with my desktop Qgis 3.44 LTR and received an error message stating that several layers could not be loaded. I need to check them in the QGIS project and adjust them. Similar projects from the past few days all went well. What is going on here, and have I lost my data? How do I get it back?
