It seems the tool has found the device correctly:

I've got a CH32V208WB board.
Now I can check this.🥲

[otipohc69]

Doesn't seems to be wchisp error related, your RDPR is protected, just run :
wchisp config unprotect
before trying to flash your board.
Does someone know how to set the registers back for RDPR?
ok made one function by myself derived frome Unprotect ConfigCommands, just replaced the first byte 👍
config[0] = 0xff; // code flash protected
seems to work....
Maybe a check of RDPR value before flashing could be a good feature
