"Invalid Disc Name" has been reported from time to time in several versions of Premiere Elements. It is not a Premiere Elements 14 specific issue.
Essentially all the cases that I have seen reported go unsolved. But, problems with the same symptoms can (often do) have different causes. So, let us go through the typical drill.
1. If you video card/graphics card is not Intel HD Graphics 2000 and newer, then please disable the preference that reads
"Use Hardware Acceleration (works on Intel HD Graphics 2000 and newer)". See Edit Menu/Preferences/General. Any effect on the burn to setup?
2. Do you have QuickTIme 7.7.6 installed on your Windows 10 64 bit computer?
and are you running the programs as administrator (from user account with administrative privileges)?
3. Even though you cannot get Expert & Share/Disc/Blu-ray with Type = Disc to show Status = Ready, can you do that if the Type = ISO (25 GB) or ISO (50 GB)?
4. Have you gone through changing the Disc Name to various formats?
5. Have you attempted to do uninstall/free ccleaner run through (regular & registry)
and then reinstall with antivirus and firewalls disabled?
6. Have you tried deleting the Adobe Premiere Elements Prefs file?
Local Disk C
and in the 14.0 Folder is the Adobe Premiere Elements Prefs file that you delete. If that does not work, then delete the whole 14.0 Folder in which the Adobe Premiere Elements Prefs file exists.
Please consider, supply more details, and then we can decide what next for troubleshooting strategy.
