"Connection errored out" when inserting the code (or /etc/passwd)

The title itself is already pretty exhaustive.

As of today, I have this problem. When I insert ANY code (length and programming language are NOT IMPORTANT) my message is NOT sent and I get a “Connection errored out” error. You can check it yourself now.

Although, ok print(“Hello, World!”) goes fine. But, for example, this code will 100% cause the error

CREATE TABLE Shops (
    shop_id INT PRIMARY KEY GENERATED ALWAYS AS IDENTITY,
    shop_name VARCHAR(100)
);

CREATE TABLE Units (
    unit_id INT PRIMARY KEY GENERATED ALWAYS AS IDENTITY,
    unit_name VARCHAR(100),
    shop_id INT,
    FOREIGN KEY (shop_id) REFERENCES Shops(shop_id)
);

CREATE TABLE Mechanisms (
    mechanism_id INT PRIMARY KEY GENERATED ALWAYS AS IDENTITY,
    mechanism_name VARCHAR(100),
    unit_id INT,
    FOREIGN KEY (unit_id) REFERENCES Units(unit_id)
);

CREATE TABLE EngineData (
    record_id INT PRIMARY KEY GENERATED ALWAYS AS IDENTITY,
    mechanism_id INT,
    voltage FLOAT,
    temperature FLOAT,
    speed FLOAT,
    timestamp DATETIME,
    FOREIGN KEY (mechanism_id) REFERENCES Mechanisms(mechanism_id)
);

CREATE TABLE RollingMillData (
    record_id INT PRIMARY KEY GENERATED ALWAYS AS IDENTITY,
    mechanism_id INT,
    pressure FLOAT,
    speed FLOAT,
    timestamp DATETIME,
    FOREIGN KEY (mechanism_id) REFERENCES Mechanisms(mechanism_id)
);

And also any mention of /etc/passwd will cause an error

The problem with /etc/passwd was there a long time ago and was fixed "with crutches" by simply inserting spaces before slashes And the problem with code insertion NEVER existed and appeared only yesterday!!!
