Float to String does not work

  Serial.println(canValue) // Working
  float dividedCanValue = (float)canValue / 10.0;
  Serial.println(dividedCanValue ) // Working
  String valueStr = String(value, 1);
  Serial.println(valueStr) // Not working (valueStr is empty)

You are missing a bunch of semicolons. The variable 'value' is not defined.

After fixing all your syntax errors, this displays:

0.00
0.00
0.0

void setup()
{
  Serial.begin(115200);
  delay(200);
  
  float canValue = 0.0;
  Serial.println(canValue); // Working
  float dividedCanValue = (float)canValue / 10.0;
  Serial.println(dividedCanValue); // Working
  String valueStr = String(canValue, 1);
  Serial.println(valueStr); // Not working (valueStr is empty)
}

void loop() {}
