First FYI only, AMD stopped supporting Windows 8/8.1. There will be no more updated drivers for your GPU card from AMD. The last driver is from 2017 for Windows 8.1: AMD Radeon™ HD 8730M Series GPU Drivers & Support | AMD
Second: Filmora may not be compatible or is in conflict with AMD Relive screen recorder. You may need to contact Filmora Support and see if their software works with AMD Driver software Relive.
Third: you can try and prevent AMD Relive from being installed when you install the AMD Driver software as per this AMD site: How to Install and Enable Radeon ReLive
If you don't install AMD Relive then see if you continue getting the error using Filmora. Otherwise you probably gonna need to uninstall Filmora and just use AMD Relive as your screen recorder.
If you don't install AMD Relive, go to Task Manager and make sure these two files are not running:
amddvr.exe
amdow.exe
