I can not delete selected faces or edges with the hotkeys anymore. Both X and Delete hotkeys are not working. Meanwhile I still can delete objects in object mode and delete and dissolve my faces and edges through the menu. I tried to reset my KeyMap, but had no luck. How do I reassign this tool to work as before? (when I was able to choose should I delete or dissolve my selected part of geometry after I pressed Delete button).
go to preferences -> keymap -> Name
scroll down to 3DView -> Mesh -> Mesh Global
scroll down until "add new"
tap on "add new"
instead of x enter whatever key you like
The name is important - must be correct with upper/lowercase sensitive
Then it should work again.
if you go in preferences -> keymap and type in "Delete" you can see in which context the delete key is assigned to.
In your case you should check the entries in "mesh". If there are more assigned then you want, you should delete the unwanted.
