admin – Magento 2.4: Uncaught TypeError: base is not a constructor

After Magento update to 2.4, I’m getting this “base is not a constructor” error which is causing other grids to unable load in the admin.
When I run the command:
->sudo chmod 777 -R Var/ pub/static/ generated
then cache flush error stopped showing but it starts showing again when I navigate other admin pages.

Please suggest some solution. Any help will be appreciated.
