How to resolve 'Error Merging File' using 1DM Download Manager on Android?

When downloading any video file over 10 MB download manager consistently fails when it reaches 100% with the error message "*Error Merging File*"? Does anyone know how to resolve this issue or a workaround outside manually merging the files? App Info: 1DM : browser and video download version 16.1 Device info is as follows : Samsung SM-G988U1 using Android 13 Tiramisu. There is plenty of space available on the internal drive and SD card, so storage capacity is not an issue.
