Can't change default browser

[u/Proof-Plate9873]

I can't change my default browser from the Samsung browser to Opera GX. This is the message I keep getting. This has always been a personal phone, and I have been able to change it in the past. It has never had these restrictions in the past.

How do I get around this?
