psr/log is locked to version 2.0.0 and an update of this package was not requested. - psr/log 2.0.0 requires php >=8.0.0 -> your php version (7.4.26) does not satisfy that requirement.
Root composer.json requires php ^7.3 but your php version (8.0.0) does not satisfy that requirement [duplicate]
composer install --ignore-platform-reqs
