Check the MySQL official document, there is a record:

Lower_case_table_names can only be configured when initializing the server. Changing the lower_case_table_names setting after the server is initialized is prohibited.

Setting lower_case_table_names=1 is valid only during initialization, such as:

-initialize-lower-case-table-names=1
