Won't this code cause EFCore concurrency exceptions?

public async ValueTask<Tag?> GetTag(string name)
        {
            if (_cache.TryGetValue(name, out object? cachedTag))
                return cachedTag as Tag;

            Tag? databaseTag = await _dbctx.Tags.FirstOrDefaultAsync(t => t.Name == name);

            if (databaseTag is not null)
                _cache.Set(name, databaseTag);

            return databaseTag;
        }

public async ValueTask<Tag?> GetTag(string name)
        {
            if (_cache.TryGetValue(name, out object? cachedTag))
                return cachedTag as Tag;

            Tag? databaseTag = await _dbctx.Tags.FirstOrDefaultAsync(t => t.Name == name);

            if (databaseTag is not null)
                _cache.Set(name, databaseTag);

            return databaseTag;
        }
