Why does my ACER Spin 3(SP313-51N)'s pen pressure suddenly doesn't work properly?

Hello. I've been using this laptop, Acer Spin 3 (SP313-51N), for about a year now and everything worked perfectly fine, until today suddenly the pen's digital pressure goes weird. Usually the pen has high sensitivity and could easily touch stuffs on the screen, but today suddenly the pen's pressure sensitivity is like very low, I need to press it really hard for it to even tap/touch anything.

Also its battery lifespan became short in just a short time. Just last week I still used it normally for my art, pen pressure still normal and the pen can last for hours. Now the pen's pressure goes weird and it can only last for like less than an hour. I figure the problem really is on the pen since the laptop's touchscreen still works perfectly fine.

I also tried restarting several times, checking the human interface device, I tried removing the window's update and installed the older window's version. But all to no avail.

Any ideas on how to fix this problem? or maybe recommendation for alternative pen (if its possible to use other pen). I hope you can give me some ideas to fix this problem since this really interrupted my work and I really need to fix this asap. Thank you😔
