Why is the solution not installed on the second Bitrix site?

Question

1C-Bitrix

We purchased the solution https://marketplace.1c-bitrix.ru/solutions/dw.deluxe/
When you try to install the solution on the second domain - taller.kz , the installation freezes at 0% at the installation stage.
We contacted the developer of the solution.
On the first domain of the license, we have an OPERATING online store - https://posudataller.ru.
The developer also failed to install either his solution or the standard store on the standard Bitrix template.
The developer said to turn to the Bitrixoids directly, who shrug.
And they broke the site on the first domain after their manipulations, although they indicated in the request that nothing should be done with the main site. I had to restore from a copy.
The solution with editing the SEARCH.PHP file did not help.. Unfortunately.
Prior to that (a couple of months ago), another solution was installed on this domain and everything was fine.
Attached is the server error log:
