Haven’t had a problem since I started using Linux full time in 2019 but I rarely boot to Windows (usually once every few months to update it). I have W10 and Kinoite (openSUSE before that) installed on separate SSDs. I used 2 EFI partitions (which I make backups of from time to time) on the respective drives the OSs are installed on.
I’ve cleared entries before with efibootmgr.
