I also had the same issues, actually i had added some third party extension and that was getting conflicted so i have removed that and i have run the command. enter image description here

  • php bin/magento setup:upgrade

    php bin/magento setup:di:compile

    php bin/magento setup:static-content:deploy -f

    php bin/magento cache:clean

    php bin/magento cache:flush

    php bin/magento setup:static-content:deploy -f en_US en_CA


To resolve this issue, please run php bin/magento setup:static-content:deploy [<languages>]. Change [<languages>] into your language, for example: en_US, en_GB,..etc
