My brush switches to eraser even if i binded it to B key

[MIRU30676123t6am]

Literally half an hour ago everything was working fine, but all of a sudden when I pressed the hot key on the pen, the brush started switching to the eraser. on the tablet itself there is also a hot key b and it works fine, but the key on the pen began to switch to the eraser. pen and drivers work fine, I suspect this is some kind of bug in photoshop or I pressed some key combination and the eraser was automatically selected instead of the brush. in simple words - there is a bind on the b key on the pen, but when it is pressed, it selects the eraser. I want to know why this is happening and how to fix it.

Hi @MIRU30676123t6am is the tilde ~ key being activated somehow? That shortcut changes a brush to an eraser.

no, i only used tablet and a pen. I almost never press keys when I work, except for combinations ctrl+z and alt

Now, I dug into the tablet settings, as it turned out that huion does not recognize programs very well and when adding Photoshop in the tablet settings, it turned out that by default the button on the stylus is designated as E key and the program associated with the tablet suddenly stopped recognizing photoshop. I changed everything back, but I still don't understand how the stylus settings suddenly changed to default
