Whether something is a problem or not is a matter of perspective. Certain problems go away when you reframe them, certain problems dont
you find a frame with the least amount of problems
death is only a problem because of a clinging to life that causes us to fear its end and despair, but clinging to death wouldn't really be helpful since we would just kill ourselves, so find a perspective where clinging to either life or death is illogical, ie a rebirth perspective
for example
really there's a frame where there's only one actual problem in life
the problem of believing there is problems, of suffering over the things we cling to and their inevitable impermanence and not being able to properly let them go when they go
if you frame that problem correctly then solve it that you can pretty much do whatever or have whatever happen to you and be mentally fine with it
we only care about what is "true" and what is "false" because we know that accurate information about reality is useful for acting effectively in reality
but one thing we have to recognize about reality is that true/false is just a construction of the mind with no absolute nature outside of our minds
we should only care about true/false for the sake of solving the one real problem, suffering, and be willing to let one perception of the truth go for a perception of the truth that will make us suffer less
and then the stuff we do in our daily lives will just not be perceived as problems anymore, and we'll live in peace, focusing our passion on solving this one real problem. the apparent solidity of life is an illusion produced by our clinging to it, and if we can penetrate that fact, we wont become dismayed when that stability inevitably fails us.
