Gravel bike gears slipping standing up

[me vs my gravel bike]

I currently own a carerra gravel bike. When I try to stand up and pedal the chain and gears slip and this nearly results in me falling off every time.
When I ride the bike I do not stand up and pedal. This means when I’m going up a hill it’s insanely hard to climb it.
What do I do as it’s very hard to ride seated continuously

How many miles have you done since the current chain was fitted? Same Q for cassette.

Standing up you're likely putting in more load than sitting, which will exacerbate the effects of wear and promote slipping.

Sounds like the chain and possibly the cassette are worn; the liklihood of which will depend on distance covered, lubing / cleaning regime and conditions... tell us more

Quick question on what you mean by slipping.

Normally this just means that the chain stops engaging with the teeth of the cassette* and then after slipping it re engages in the same gear.

But it could also be misaligned/mis-indexed rear mech doing a sudden uncommanded gear change during which the chain slips while changing and you end up in a different, higher, gear.

Or it could mean the chain skating over the teeth of the chainring. When this happened to me it was when changing to the (worn out) big ring.

* Spell check wanted me to say casserole. That could be interesting.

Another option could be a sticky freehub.

Plus, a notable absence of manners..
