# DSolve Throw::nocatch: Uncaught Throw[\$Failed,balancefail] returned to top level. error in 11.2 [closed]

Reported also to WRI. [CASE:3965533]

I am in the process of updating Kamke differentional equations tests for 11.2 when encountered a new error I have not seen before on one of the Kamke ODE's (number 1586 in the Kamke book).

Could someone explain why this comes up now? Is this a new bug or a known issue?

ClearAll[y,x,A,a];
n=5;
ode=x*D[y[x],{x,n}]-(a*A[1]-A[0])*x-A[1]-((a*A[2]-A[1])*x+A[2])*
y'[x]-((a*A[3]-A[2])*x+A[3])*y''[x]-((a*A[4]-A[3])*x+A[4])*
y'''[x]-((a*A[5]-A[4])*x+A[5])*y''''[x]==0;

DSolve[ode,y[x],x]


Which gives

No such message is generated in 11.1
