[mpm_winnt:crit] [pid 3316:tid 436] AH02965: Child: Unable to retrieve my generation from the parent

First of all, I’m Japanese, so I’m not very good at replying or explaining things. Please understand that first.

I installed the on-premises version using Xampp on my local PC.
It is intended for backup of UA.
The Google Analytics Importer plugin is already installed.
We have responded by referring to the following.

There was no problem so far, but when I try to import it, after a few minutes it says “killed” and I can’t import it.

When I check the matomo log, there is only one line:
[mpm_winnt:crit] [pid 3316:tid 436] AH02965: Child: Unable to retrieve my generation from the parent

Please help me.
