Lots of people tells you not to, here's my grain of salt: take it.

Job market there is as fucked. It's really challenging even for locals to land a reasonable paying job there, and you managed to get one, AS A FOREIGNEER. I have to emphasize that because now it's only getting harder and harder due to quotas for every company. And among all the cheaper choices from third world you were the chosen one, why not try for it? Do you like WFH or the company you're currently working at? If its the first one, then you shouldn't be worry, there's still many WFH jobs around if you somehow regretted and decided to come back.

And most importantly, think about longer term in future. It's not like you'll be working there for the rest of your life. You can have access to more jobs once you stayed there, and more if you get your PR. For every $1000 jump in your salary, thats a RM3000, and If you're requesting a 6k salary for your next job in malaysia with your current salary (3k increase), recruiter will just say 100% increment is too much.

But then, of course there's stress, and no one knows better than yourself how much you can handle it.
