Performance improvement, predicate system linq queries

I'm trying to redevelop a news system on a management asp net core app. We can post an additionnal information about a user or a company, and these informations works with rights (a user is allowed to see or no with his function).

I'm using Entity Framework Core, and I've some problems with performance.. I'm student, my code is certainly horrible for you ^^

See that :

I tried to remove the ToList(), but it's throwing an error than there's another request by another thread... MY DbContext Lifetime is Transient

That seems you have one open connection via DbContext, but IQueryable will work async or will do async computations on your code, and after a while your computation takes much time to finish previous sql execution then it will block next/another sql execution on IQueryable, because you your query is conflicts on DbContext, it is inevitable.

i assume you know differences between IQueryable and ICollection

My Suggestion, Try to use SQL Stored Procedure to simplify your codes, in your code you are overloading too much on the hosting server. You can distribute between sql server and hosting server your computations.
