Fiddler doesn't work recently because Chrome and Edge don't trust fiddler certificate which expires in 2025. So fiddler certificate is valid. The chrome version is Version 123.0.6312.59 (Official Build) (64-bit). But I don't think that is due to chrome because Edge has the same problem. I have another machine with same fiddler version and chrome version and it works. My OS is Windows 10.
In fiddler:
