you could try using Mods to enable the console.
you'll need:

Bepinex:
https://valheim.thunderstore.io/package/denikson/BepInExPack_Valheim/

and after installing Bepinex, install this:
https://www.nexusmods.com/valheim/mods/669

follow all the install directions for both mods, (its not hard....)

F5 should work after all is installed and world is loaded.
