If you manage to get the update.app file for your model , download the "Huawei update extractor" and extract system & boot images , then flash them through fastboot , when your device fully boots and you set it up , flash the stock recovery through fastboot

Beware that sometimes your the setup freezes and then you'd have to factory reset through twrp or stock recovery , but if the recovery is also not working properly , it would be hard to flash twrp to factory reset .

I advise you to leave twrp , as we probably will not get anymore updates via ota.
