Fix beer that is too light.

Hello,
I brewed a beer last week with the thermometer not correctly fixed into grainfather. That resulted to a mash temp > 70°C instead of 66°. I noticed it after 10-15min and cooled it. OG was as expected (1.045).
Now, I tested the beer after 8 days and it's... very light. I still have a Dry hopping to do but not sure it will help on that side.
It's stuck at FG 1.022 instead of 1.011.
Also, I noticed that the Malts I took where not exactly the same than those in the recipe. For example, I bought Crystal instead of dark Crystal. EBC was supposed to be at 34 and after updating the malts in the recipe it's 11.
And... I used my own hops. Not sure about the alpha acid or harvest time but bittering hop is not mine. There could be many reasons.
OG (SG)1.045
FG (SG)1.022
EBC (Color) 11
IBU (Bitterness) 28.5 (---> not so sure)
ABV (Alcohol) 3.15%
I find it extremly interesting to be honnest. But I'm wondering if I should try to change something in the fermenter or just leave it like that and have an extremly light beer.
What would you do?
-Nothing
-Bottle half without changing anything and change the rest? (Is that feasible?)
-Add sugar or fruits or IDKW for the second part ?

What were the actual ingredients? What was the yeast? What was the fermentation temperature?

For light, do you mean ABV or color?
If it's ABV, taste it first to see if you think it's drinkable once it's carbonated. If it isn't you could look at some of the yeast that will break down the complex sugars you have from the hot mash. That's either a Sacchromyces diastaticus strain or Brettanomyces.

It's this recipe https://brewdogrecipes.com/recipes/prototype-challenge-moshi-moshi-15
but with us-05 and Malts with lower ebc and my own cascade and centenial hops. It was fermented at 18°c during 6days, with dry hopping of 150gr for 48h after 4 days. Since 3 days at 20°C.

It's ok to drink but I find it a bit light in ABV and maybe malt. It's not like water but probably more a session? I'm used to beers with a bit more flavors. But maybe the second dry hopping will change that?

It will add more flavour and some hops will add some enzymes. I can't see it making much of a difference to the ABV though.

Just my $0.02.  chalk it up to lesson learned.
Anything you do after\during fermentation will make it worse.
Maybe blend it in another very strong batch?

Add the second dry-hop for a bit more punch and call it a day.
A session IPA can be a great thing.
