Excel Like Product Manager Importing partially

My client is having some problems with their import, just updated to recent version  but when submitting a 4,000  product CSV (with variations) it says it has processed 1999 items and redirects to the product list.

Is there any configuration or constant flag we are missing?

As attached you may see the IDs in the CSV do exist and are not being updated (in this case im trying to update the SKUs)


We need to manually slice the CSV in files with less than 1900 items so they import correctly

And it used to work fine

No timeouts or error,  we have tried to update 70 items per loop but still just updates up to 1900 items

Yeah just stops after 1900 on different files nothing weird in the files.

Here is a validation result
csvlint.io/validation/5e989f38a1df500004000023
says  encoding ASCII-8BIT, but final one is uploaded in UTF8

Version 2.0.62 worked perfectly, should we rollback?

I rolled back to Version 2.0.62 (like 3 years old code, not 2.1.62)

The contents of the line 1901 are not the issue, I have to break large files in files below 1900 lines then it imports fine, but of course it's not convenient for the client so rolling back the version was the best option
