[Magento\Framework\Exception\FileSystemException] File "D:/xampp/htdocs/zenmeds/var/view_preprocessed/pub/static/frontend/Magento/blank/en_US/info.json" cannot be opened Warning!fopen(D:/xampp/htdocs/zenmeds/var/v iew_preprocessed/pub/static/frontend/Magento/blank/en_US/info.json): failed to open stream: Permission denied
Key to the answer is "Permission denied". I am unfortunately no windows expert. But seems like it is answered here.
The error is saying that var/view_preprocessed/pub/static/frontend/Magento/blank/en_US/info.json is not openable by Magento cause can be the wrong file permission.
Solution: Make a practice( what I prefer ) to run Magento commands as sudo if you are in linux machine to avoid such errors such as
sudo php bin/magento setup:static-content:deploy
