From Google Translate:

Hello sir, I found during testing that this statement has GC. Is there any way to solve it?

@32haojiufangjia yes, please try

_group.AsEnumerable().AsParallel().ForAll(Execute);

Fyi, when doing things in parallel, please avoid using generated methods like entity.AddXyz(), entity.ReplaceXyz(), entity.RemoveXyz(), etc, since they result in modifying non-concurrent collections like HashSets, etc. When doing things in parallel I recommend changing the component values directly, e.g.

entity.health.value -= 1;
