OSx Win10 Dual boot stopped working

Hi I have a uefi system PC with Catalina and Windows 10 on separate drives. Usually I would press F12 to access the boot order and choose whatever I need but now Windows is always the first to run.

This came after a screen before the boot asking me to reset the nvRAM which I did.

Now the only way I have to boot Macalina is to disconnect Windows drive.

Any quick solution to this please. Can't find anything at all. I keep seeing the clover thingy but I never use that. Cheers
