Which TBC version?
What job-file/Access version? Is the latest, or at least the minimum necessary, office converter installed? Software and utilities (trimblegeospatial.com) - section "office software updates"
Have you tried importing it into a different TBC version? I always encourage to keep previous versions, i.e. post 4 here Trimble Business Center 2024 truncating feature codes | Trimble Business Center
Does it contain a scan or other unusual data?
Are feature codes and a FXL file involved?
Has the project been saved already, or has it just been created from a template? Is the TBC project management folder located on a network drive? A new project is temporarily saved in that folder before saving it to its final location.
In any case, is the project located on a network drive?
Could you upload the JXL here?
