Depending on where you work, your employer may be able to take that personal device you’re using for work in the event of a lawsuit against the company (where they need to retain anything that may be relevant to discovery), or in the event of a security incident (where they may need it for forensics).
I work in information security, and I practice strict isolation for that exact reason. Two laptops, two phones, because if anything ever happens they can and will take devices for analysis or evidence. If you are using an issued device, they’ll assign you a new one; if it’s a personal device you’ll get it back when they’re done with it, which could take years.
Edited to add this is dependent on your employment contract, but it’s better to be safe than sorry. Cover your camera and use your work computer.
