typing problem: by typing space, it deletes my previous word / words / contents.

It only happens on a few platforms (most heavily: google chrome, especially in the search bar and in the cells in google sheets - where I work most of the time).

When I type a word (as normal) then follow it with a space to continue typing the next words, right after I type space the previous word (before the space) got deleted. When I retype it, it was fine. As this always and only happens upon first-time input. (ie. I chose a new cell in google sheets then type and this error happens, but I retype in that same cell it was fine - the same is with google search bar).

It happens every single time, which results in me having to spend twice as much time (to retype everything). And it's only occurs: upon first input and with the first word / first space.

But it's annoying. I've checked every preferences / threads to find the same problem but there apparently is none. Pls send help I'm dying of small but repetitive discomfort.

I use macbook pro 17. this happens on both version (catalina and the previous that i suddenly forgot its name)

Thank you all.
