Your requirements could not be resolved to an installable set of packages.
Problem 1
- Root composer.json requires wyrihaximus/async-test-utilities ^4.2.2 -> satisfiable by wyrihaximus/async-test-utilities[4.2.2].
- wyrihaximus/async-test-utilities 4.2.2 requires react/promise ^2.9 -> found react/promise[v2.9.0, v2.10.0, v2.11.0] but it conflicts with your root composer.json require (^3.1.0).
Problem 2
- wyrihaximus/ticking-promise 3.0.0 requires react/promise ^2.8 -> found react/promise[v2.8.0, v2.9.0, v2.10.0, v2.11.0] but it conflicts with your root composer.json require (^3.1.0).
- wyrihaximus/ticking-promise 3.1.0 requires php ^8.2 -> your php version (7.4.7; overridden via config.platform, actual: 8.3.0RC6) does not satisfy that requirement.
- Root composer.json requires wyrihaximus/ticking-promise ^3 -> satisfiable by wyrihaximus/ticking-promise[3.0.0, 3.1.0].
