Why did non-csrf forms abruptly stop being sent?

Question

Yii

just worked and now everywhere in all forms, without exception, falls error 400 Bad Request
for orthodox here csrf 'd0ee39aee894ffc9b6d42d4f87debe40e8eda9554fcc6b86b85f370261bd0b1da: 2: {i: 0; s: 5: \ "_ csrf \"; i: 1; s: 32: \ "GIbpFnsIsgItxlnjiMy5p8oBr5M1wD0K \";}'
I understand that I'm stupid somewhere, but here's what the debugger says
8 07:41:51.213 trace yii\base\Controller::runAction Route to run: image/
create 400 exception 'yii\web\BadRequestHttpException' with message 'Failed to validate submitted data.' in C:\OpenServer\domains\film.lc\vendor\yiisoft\yii2\web\Controller.php:110
