Loss of the reverse gear is a mechanical failure.
Knowledgeable mechanic can quickly determine by performing a ‘manual low’ test during short 1/10 mile test drive.
It’s an easy test - difficult to explain here online.
If the engine revs but the vehicle does not move appreciably in reverse, it sounds like the reverse band may be damaged or burned up inside the transmission. How is the fluid level and condition? Any signs of concern there?
Further, diagnostic testing can indicate shift solenoid position and gear selected to see if the electronic portion is working properly (I suspect it is).
