History says that the answer is yes.
I have read a lot of posts on LinkedIn about how employers will understand because "there is a pandemic going on."
Unfortunately, discrimination against the long term unemployed became prominent during the Great Recession and I doubt that anyone was unaware of that.
The assumption, if someone has been unemployed for more than 6 months, is that many employers have had their resume cross their desk and said no. People tend not to want to go against the crowd consensus and because presumably hundreds of other employers have rejected you, employers assume that rejecting you is also the wise choice.
A pandemic may make it less likely that employers have sifted through and already rejected you, but that risk is not going to go away. Them understanding doesn't reduce the risk to them as employers.
How do you mitigate this?
Basically you should find something to do.
Have a friend with a startup? Ask them to give you a job, even if it is 4 hours a week. A friend who was struggling to find his first software engineering job (he had no internships) solved it by working for a startup a friend ran for a couple months.
Or you could do some open-source work. Or you could have your own startup project.
