Your requirements could not be resolved to an installable set of packages. Problem 1 - Root composer.json requires composer/pcre ^3.4, found composer/pcre[3.4.0] but these were not loaded, likely because it conflicts with another require. Problem 2 - composer/composer is locked to version 2.2.29 and an update of this package was not requested. - composer/composer 2.2.29 requires composer/pcre ^1.0 -> found composer/pcre[1.0.0, 1.0.1] but it conflicts with your root composer.json require (^3.4).
