This worked for me on Win. 10 for Saving Error 102348.
(may not be exact wording, but close...)
DO NOT CLOSE TT and loose your data...
1. Windows Security App (search in the box at the bottom left)
2. Virus and Threat Protection - Manage Settings
3. Controlled Folder Access
4. Allow an App to access folder
5. + Add an allowed App
6. The "Recently" block apps should show TT2024. Click on each one.
7. Mine TT file then save fine.
