If it was mine I would take it out of the pot. Replant what is alive in a smaller pot. Evergreen Agapanthus need to be under glass over winter in the UK. There is another thread at present that might be helpful.
I have worked as a Gardener for 24 years. My latest garden is a new build garden on heavy clay.
I don't want to take over the original post, but I have been growing agapanthus in pots outside since 1969 (moon landing). I now have five "hardy" varieties that have not appeared this spring. (Forgetting my two evergreen plants wintered in an unheated greenhouse - I have already written them off.)
In your case, I would follow Suze's advice.
In my case, it is back to th drawing board.

@bede I have a deciduous one in the ground that is just hanging on.
Elsewhere I have three plants of A Navy Blue. Border is west facing and they are planted close to a path. As they emerged this spring I have covered them with buckets one cold nights and they are doing well. Navy Blue is an excellent form always flowers well for me with a weekly feed. It is classed as a semi evergreen but it always dies back here.

@punkdoc Yes I understand your thoughts. It would be interesting to know if this winter has been a problem for growers in the south and west? It can be difficult giving advice when you don't know where a poster lives, I try to be to be cautious.

My deciduous ones - all planted in open ground - seem to be coming back OK. The biggest, latest ones aren't up yet. That may be because I've lost them or just that they aren't up yet. I have lost my evergreen ones that were outside in a pot in a very sheltered spot. They've been out for nearly ten years but this winter has killed them

I would take issue with @GardenerSuze, re evergreen Agapanthus, they do not need over wintering under glass in the whole of the U.K.
One deep blue evergreen aga is in a border at NT Polesden Lacey (appologies if wrongly spelt). On a south-facing border and mulched over winter. Polesden Lacey is definitely UK.
Evergreen agas have colonised the Penzance area. I haven't yet visited after this winter, but they survived, untouched, the "beast from the east". Some locals don't think of Cornwall as England.
I have an "Irishman's cutting" (apologies if that is not politically acceptable) from Sennen. It is dark blue, 3-years old and has not yet flowered; it may, just may, have survived in my cold greenhouse.

As a young marketing Turk, I was trained not to say "problem", but to say "opportunity". The people in cutomer services used to substitute "issue".
