Unfortunately. yes.

I have not seen this big in the news (yet) so thought to provide a heads up for those experimenting (and not knowing).

Hopefully it gets addressed in an updated revision but that might be a though one.

So to summarise: the RP2350 (Pico2) has an electrical fault on the GPIO pins which doesn't exist on the earlier RP2040 (Pico).

MT+86 & Turbo Pascal v1 on CCP/M-86, multitasking with LAN & graphics in 128Kb.
Logitech, TopSpeed & FTL Modula-2 on bare metal (Z80, '286 protected mode).

In short, yes. see also 2.50 minute video: https://www.youtube.com/watch?v=sqJQNF9sna

I mentioned it here because it was the first discussion I could find that mentioned people wanting to experiment with products containing the RP2350.

Well, I guess that's a cautionary tale: if linking to YouTube at least annotate it with the name of the originator :-/

Way /way/ back, it was considered bad form to use a machine-generated URL which wasn't even minimally descriptive of the content. Then along came Notes/Domino, "Enterprise Grade" stuff from Netscape, and the floodgates were opened...
