it seems to be driving good (besides the fact it won’t boost) I just want to make sure that it won’t be detrimental driving it like this until I can find someone to weld it for me, I used a wire to kinda help it

You're good. If it won't boost it is open. That won't cause any issues besides being slow as a slug.
Wired closed on the other hand would cause over boosting and lead to detonation/knock or possibly worse.

I actually wire mine open when I have to get emissions testing done so the "tech" doesn't accidentally boost it while on the dyno rollers.

I have an external wastegate on the manifold does keeping it open still apply?
