Sure, it doesn’t happen often. Those mechanisms are often just some software running in some microcontroller, which can also fail and manifactorers like to cheapen out where possible.
It did happen to me maybe 2 times in >5 years, where not even long pressing power button helps. I was traveling by rail the last time and luckly had my ticket physically.
Honestly that is mostly solved, all have some mechanism to reset it even if is completely frozen. Plus nowadays is not a that common occurrence.
