For your first problem:

Change setting for "Import Language Override" - language_code_only

to *any* other value.
For example, change "Import Language Override" from language_code_only *to* language_id_only

SKIPPED! - v_products_model: 20230710269 - No category provided for this new product importing with: language_code_only
SKIPPED! - v_products_model: 20230710270 - No category provided for this new product importing with: language_code_only
........

sure i have tried to check the data in file,sure it right,and there imported more items with same category,but it stop and display this error now.
and i sure i have try to fix any data file,and it always display this error,and i sure i have checked the category and it in my shop.
maybe have quantitative restriction in code?
For second problem: Please identify the fields in your import file. The fields are the first row of the file. For example: v_products_model

It is possible that the file is too large to import all at once. There is a split option to allow making multiple smaller files from a single large file. I do not believe the file size is the problem. I received a copy of your debug log. When I know the field names, I expect I can determine a solution.
