sokolov@sokolov-HP-Pavilion-Laptop-15-cs1xxx ~/P/c/backend-application> php7.4 (which composer) install
The "joshbrw/laravel-module-installer" plugin was skipped because it requires a Plugin API version ("^1.1") that does not match your Composer installation ("2.0.0"). You may need to run composer update with the "--no-plugins" option.
The "wikimedia/composer-merge-plugin" plugin was skipped because it requires a Plugin API version ("^1.0") that does not match your Composer installation ("2.0.0"). You may need to run composer update with the "--no-plugins" option.
Installing dependencies from lock file (including require-dev)
Verifying lock file contents can be installed on current platform.
Warning: The lock file is not up to date with the latest changes in composer.json. You may be getting outdated dependencies. It is recommended that you run `composer update` or `composer update <package name>`.
Your lock file does not contain a compatible set of packages. Please run composer update.

  Problem 1
    - joshbrw/laravel-module-installer is locked to version v0.1.4 and an update of this package was not requested.
    - joshbrw/laravel-module-installer v0.1.4 requires composer-plugin-api ^1.1 -> found composer-plugin-api[2.0.0] but it does not match the constraint.
  Problem 2
    - wikimedia/composer-merge-plugin is locked to version v1.4.1 and an update of this package was not requested.
    - wikimedia/composer-merge-plugin v1.4.1 requires composer-plugin-api ^1.0 -> found composer-plugin-api[2.0.0] but it does not match the constraint.

You are using Composer 2, which some of your plugins seem to be incompatible with. Make sure you update your plugins or report a plugin-issue to ask them to support Composer 2.

I was able to solve this problem with

php7.4 (which composer) install --ignore-platform-reqs

I used composer 2

That issue was solved in v3.4.4.
