Make sure you have right permission for folder generated and pub(basically this folder will be in correct permission and you would have got 500 Internal server on installing or accessing the site after installation).
make sure generated folder is having 777 permission.
try to clear you web static content and add it again.
php bin/magento setup:static-content:deploy
if it said already exists or like that,
php bin/magento setup:static-content:deploy -f
force it with
command like above.
Already some of the similar questions are available from other users.
