41R is not a standard 5% value.
Normally 5% tolerance resistors are only made in E24 values i.e. decade multiples of: 10, 11, 12, 13 , 15, 16, 18, 20, 22, 24, 27, 30, 33, 36, 39, 43, 47, 51, 56, 62, 68, 75, 82, 91. This is why you often see values such as 2k2 or 68k and almost never 90R or 52R.
Of course there are exceptions, for example 50R is used for RF loads and you might be able to buy 8R and 4R as audio dummy loads but 41R is a non-standard value without any common use so it's unlikely you'll find it.
Check the value again.
Get someone else you read it. You might have a very mild form of colour blindness and not even be aware of it..
Is the resistor discoloured? Does it look burnt?
The value is 5% tolerance which means it can range from 38.95Ω to 43.05Ω so if you're certain it's 41R, just replace it with the nearest E24 value, 43R or 39R and it should be fine.
