Magento2 – Running di:compile stops at 57% in magento 2.3.2

Class MagentoFrameworkMailEmailMessageInterfaceFactory does not
exist Class VendorExtensionModelMailTransportBuilderInterceptor
generation error: The requested class did not generate properly,
because the ‘generated’ directory permission is read-only. If —
after running the ‘bin/magento setup:di:compile’ CLI command when the
‘generated’ directory permission is set to write — the requested
class did not generate properly, then you must add the generated class
object to the signature of the related construct method, only.

I found some solutions but none worked.

Thanks in advance,
