i think op's webviewextras library has gone missing. it was always meant to go in the additional libraries folder, not in b4a's main libraries folder. if that is where op had webviewextras, and if he deleted the anywheresoftware folder before installing version 12.2, he deleted webviewextras. he may need to download it again and put it in the additional libraries folder, where it belongs (technically, nothing's stopping him from putting it in b4a's main folder, but he'll only have the same problem the next time he deletes that folder). if the library actually is already in the additional libraries folder, then it is possible he needs to select it in the ide's libraries tab. i, along with many others - some of whom have already valiantly stepped forward - use it regularly.
