That's not the forum to ask for features, open GIMP, go to Help ➤ Bug Reports and Feature Requests, your browser will open, you're on the right website.
Having said that, it's not by uninstalling and re-installing GIMP countless time that you will solve any problem, this is a typically a Microsoft's user behavior which is not the right behavior...
When you got a problem ask why, more often that anything else ➤ it's a wrong user setting that the user forget or is not aware to have changed.
BTW, asking is also learning...
If you do not want to ask in a forum like here, or to the GIMP team (Help ➤ Bug Reports...), renaming the folder "2.10" to something else or deleting it, will "reset" GIMP to its default settings as if you installed GIMP for the first time when restarting GIMP after this action.
The "2.10" folder is your Profile..., deleting or renaming it will force GIMP to recreate a new profile when starting, like a brand new GIMP.
Where is that "2.10" folder on your system ➤ https://www.gimp.org/tutorials/GIMPProfile/
