Why is MATLAB Coder crashing with assertion "Assertion at B:\matlab\​src\cg_ir\​classic\cy​cle_equiv\​CycleEquiv​alence.cpp line 216: In getClass: edge has no entry in CycleEquiv​alence::ge​tClass"

MATLAB Coder in R2021b crashes during the "Check for Run-Time Issues" stage. In a crash log, I found the following assertion:

Assertion at B:\matlab\src\cg_ir\classic\cycle_equiv\CycleEquivalence.cpp line 216:
In getClass: edge has no entry in CycleEquivalence::getClass

How can I prevent this crash?

The crash is caused by a bug in MATLAB Coder App R2021b and R2022a:

A possible workaround is to uncheck the "Collect MATLAB line execution counts" setting.
