1. Reboot the router via pulling and reconnecting the power cord
2. Log in to WWW interface
3. Go to Administration > System. Enable SSH (enable login/password as well, choose a port of your taste)
4. SSH to your router: ssh [email protected] -p 2424 (assuming your user name is admin, the IP is 192.168.50.1 and you chose port 2424 for ssh). Password is the same as for the web UI
5. In SSH session, type: rm /jffs/asd/chknvram20230516

Seems to have done the trick for me.
