The query had to wait X seconds for MemoryGrant during execution and slow query execution in SQL Server Web Edition 2012?

Question

SQL

Good afternoon!
I ran into the following problem: the query began to run for a very long time, while the query plan on the SELECT block displays an exclamation point and the message: "The query had to wait 25 seconds for MemoryGrant during execution" .
The query itself is relatively simple, there are indexes on the fields.
I haven't been able to figure out what the problem could be yet, I haven't had similar situations before.
I will be grateful for help.
