Kernel quits while using DSolve[ ]?

I tried with numerics with NDSolve the kernel shutdown looks like a bug on Mathematica 12.2.0

Maybe you can try:

    solution = 
     Block[{Integrate}, 
        DSolve[Rationalize[{DE1 == 0, displacement[0] == 0, 
            DE2 == 0 /. X1 -> length}, 0], 
          displacement[X1], {X1, 0, 3/2}] /. {Integrate -> 
           Inactive[Integrate]}] // Simplify // Activate

but answer is very complicated solution by InverseFunction and Integrals. I don't have time to solve this problem.

Regards M.I.

Thank for your help. Yes, I had also tried changing the code, as there are two DEs with one BC associated with each. But both the DEs are related, in a way creates a non-solvable loop, at least this is what it seems. There will be way to set up the problem differently, for it to be solved. I will work on this. Thanks

I reported the NDSolve crash as a bug.
