i uninstalled 2FA and tried installing by this command.
`[abhidnpc@server319 community]$ composer require ianm/twofactor:1.1.1
./composer.json has been updated
Running composer update ianm/twofactor

Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires ianm/twofactor 1.1.1 -> satisfiable by ianm/twofactor[1.1.1].
- ianm/twofactor 1.1.1 requires flarum/core 1.8.3 -> found flarum/core[v1.8.3, v1.8.4, v1.8.5] but the package is fixed to v1.8.2 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.
Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.
Installation failed, reverting ./composer.json and ./composer.lock to their original content.
