Heh, some module used by c8 has a bug. c8 was newly updated. Let's wait until they fix it.

Yet it WFM locally.

I was able to repro it. It worked with Node 25.6.1, but not with 25.7.0. It clearly a bug of yargs (used by c8).

Relevant bugs:

• Crash on node v25 bcoe/c8#582
• Node.js v25.7 breaks yargs v17 yargs/yargs#2509

It looks like c8 was supposed to update dependencies and it didn't relying on the old yargs version. Let's wait for the update. Sigh.
