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 struggling with the same error recently. I downgraded Composer to 1.9 and deleted my composer.lock file, it resolved that error you are having.
Downgrade composer:
Remove composer.lock file:
There is a file called composer.lock in your Magento root folder. Delete it or move it just in case.
Then just run the command you did before.
