This is not a fabric issue.

The full error message is:

[14:38:48] [Render thread/WARN]: Invalid floating point value for option textBackgroundOpacity = 
java.lang.NumberFormatException: empty String
	at jdk.internal.math.FloatingDecimal.readJavaFormatString(FloatingDecimal.java:1842) ~[?:?]
	at jdk.internal.math.FloatingDecimal.parseDouble(FloatingDecimal.java:110) ~[?:?]
	at java.lang.Double.parseDouble(Double.java:651) ~[?:?]
	at net.minecraft.class_315$2.method_33678(class_315.java:429) [client-intermediary.jar:?]

Which means your options.txt in your minecraft folder is corrupted.
But this is just a warning, it should not stop the game loading.

You can try renaming your options.txt to options.save (or whatever) and minecraft will recreate it with default values.
