Question: Maple 2018.1 Gets stuck when trying to manipulate expression

Maple 2018 memory usage increases as I try to display or manipulate the expression presented in  test_maple2018.mw. The same worksheet works perfectly in Maple 18

I've tried both in Maple 2018.1 and Command Line Maple 2018 obtaining the same result

Maple 2018.1, X86 64 WINDOWS, Jun 8 2018, Build ID 1321769

From command line maple 2018 when trying to evaluate

Interrupted

I was wondering if my Maple 2018.1 installation is corrupted. Since I have no acces to other Maple licenses, can anyone try to execute it? test_maple2018.mw
