WhatsApp doesn't restore chats from backup

Samsung A54, which had WhatsApp installed with two phone numbers, broke down. Google Drive contains backups of both the phone itself and WhatsApp chats (size 3.1 GB). I'm trying to set one phone number on Samsung A7 as a second number. WhatsApp detects the backup but cannot restore it due to an error. If you choose to restore chats from an old copy, the recovery process holds on. This happens with each of the two phone numbers, that is, it does not depend on the size of the backup. At the same time, if you skip restoring chats, WhatsApp still restores everything except chats in the amount of 3.1 GB.

Has anyone met a similar situation and is there any way to restore chat history?

P.S. There is no option to reinstall WhatsApp, because there is no access to the main number on the Samsung A7 and no way to receive SMS.
