I have a Magento 2 multi-website with each website has their own store view, after I upgrade it from 2.5 to 2.3.3, the main website is looking fine, but the others are broken and when I inspect, got an error like this:

(index):1 Refused to apply style from 'pub/static/_cache/merged/0cb08dac7714064caf47f5c9bb91fcb6.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled.

enter image description here

* I already deleted the pub/static/frontend and make sure the pub/static/.htaccess is there, and run:*

bin/magento cache:clean
bin/magento setup:static-content:deploy -f

but still got the same error

Your versioning is enabled due to this it is looking like that. So please run the following SQL query for the core_config table.

insert into core_config_data (config_id, scope, scope_id, path, value) values (null, 'default', 0, 'dev/static/sign', 0);

And run deploy command

bin/magento cache:clean
bin/magento setup:static-content:deploy -f

Give permission if required to var, generated and pub/static

For more information please check that reference for versioning issues.

Run this command: 

bin/magento cache:clean
bin/magento setup:static-content:deploy -f

And after -f, add lang corresponding with each of your website
