Hcaptcha fails to load as long as I have rechaptcha 7.0 module enabled. When I looked into it, it looks like the manifest file in hcaptcha iframe does not load. instead cloudflare is "checking browser" when I inspect through the hcaptcha iframe.
@clarabellerising Already took these actions but didn't help. I've ended up reinstalling Windows. Now everything works. Hopefully won't have this problem again
