One thing that no one has mentioned is that the tenure is showing as "ask agent". That makes it seem it is leasehold, which would put off many buyers. If you're not sure of the tenure pay the small fee to the land registry and check the title. If its Freehold you want that in the listing. Its also link-detached, not detached, as you share a wall with next-door's garage.
That aside I agree with pretty much everything everyone else has said. It would need to be the best priced property of the type (including 3 beds as competition because most people who want 4 bedrooms want at least 2 good size doubles) to get one of the scarce buyers in the current market.
The outside needs tidying up, including the soffits and facias. It is clear looking at the previous listing that you have changed quite a lot, it looks like the size of one of the bedrooms was reduced to increase the size of a bathroom? You have improved some of the decor from the 2017 photographs, but its fundamentally the same house and while the market in most places is probably still higher than in 2017 if I were a prospective buyer in your market (which I am not), I would not be thinking that the changes made justified a price £100,000 more than it was in 2017.
I am in a different location and as someone who has always watched my local property market on rightmove, prices are currently nosediving, the properties that are showing as SSTC in my area are either very significantly cheaper than the competition or are issue free. A house near me the sale was agreed a few months ago within 2 weeks of going on the market and completed just before Easter, the property was very well presented inside and out, and was correctly priced on the day it was listed.
I would say you either need to drop the price significantly or take it off the market until the market improves.
