First,using a hot air station to do you rework is a bad idea. Usually real rework stations are used “Louis rossmann on YouTube” does an example of gpu not working due to a heat gun job. He replaced it with a high quality rework machine that heats the top and bottom at a specific temp and measures everything. Unfortunately it’s very expensive to buy one…
Reheating the gpu with lots of flux and reasonable temp and airflow is ok. But you said you took it off. If that’s what you meant,did you reball it? Or did you just drag solder over the pads and toss it on? You HAVE to reball it with very very similar size balls. The gpu sits on these balls. Putting it on with a heat gun is a gamble,even if you’re Louis rossmann.
First,don’t power it on again. If you attempt this yourself,you’d need a reballing stencil,premade solder balls(not paste it squishes under the stencil and makes uneven balls on large chips),and good flux. You need to flatten(probably best to wick a gpu) pads on the logic board. Then reball the gpu. Use plenty of flux and hot air it back on. You have to be sure it’s seated though.
Currently,there’s a really high chance you shorted something too,depending on the strategy you used. But Louis rossmann’s videos would help you most I think.
Also,not starting doesn’t mean it’s the gpu. There are so many possibilities for boot looping.

What does the onboard diagnostics telling you?

When I plug it in, the first indicator light flashes briefly, then I can’t get anything else by clicking the power button or anything.
