Welcome to the forum
What exactly is the problem? The launcher doesn´t start or the game crashes while loading?
There may be different reasons for the same problem on both computers. May be the crash (?) caused on one of them.
Here are some possible solutions:
- start the Enderal Launcher.exe, tesV.exe and skse_loader.exe as administrator.
- please make sure that your antivirus, Windows Defender, “File System Access” and Firewall don't block the Enderal Launcher.exe, tesV.exe and skse_loader.exe
- don't launch the game with the skse_loader.exe, but via steam
- try restarting steam or your PC
- (de)activate ENBoost, OSAllocators and/or OneTweak
