    Thank You So Much Kishan Savaliya For the best solution but before removing vendor & composer update, we need to edit composer.json file and in this we need to add required dependency modules from M2.4.3 in require-dev section. Commented Sep 21, 2021 at 7:46
  • Yes true, that is required. But in above screenshot your composer was skipping module from downloading. :) Great this solution works for you. Commented Sep 21, 2021 at 16:25
