Sounds very similar to an issue from another thread, if would be worth a shot to test their solutions for your scenario:
- Set “Asset Editor Open Location” to “Main Window” in Editor Preferences.
- Change the Default RHI in Project Settings → Platform → Windows to be something other than DX12, DX11 appears to work.
- Alternatively, open a new project using UE 5.4.4, and check if the issue is present there as well
