Site is crashed when installing Shipping and Payment Method per Customer Group for Magento 2

Question:

When I upload this extension and run the install commands using SSH, the whole site crashes.

All the images are gone and in the frontend the whole layout is destroyed.

When I run a backup file with only files (not database), everything is working again.

Answer: 

In this case, we assume that the root of the issue might be due to your site’s language is not en_US.

Therefore, you need to add the language that you use into the command, in order to run deploy precisely.

For example: 

If your site uses nl_NL language, then you need to run the command as:
php bin/magento setup:static-content:deploy nl_NL en_US

Or run

you should run php bin/magento setup:db-schema:upgrade after enable module.

to create table again in case it's lack of our table

Please note that it's just the solution for your reference.
