It would be good to know what that 3rd party package was. @Ponce-De-Leon just upgraded as well and it seems to be working fine I presume?
Generally speaking, kernel upgrades are a good thing but they can introduced bugs from time to time. That's where things like rollbacks using Timeshift or similar come in. I've only experienced an issue like this once, with Linux Mint. Unfortunately my solution was to install from scratch — as I wanted to try other distributions — it so I cannot offer any troubleshooting advice.
Dual boot can be tricky, and Microsoft has been hard at work to make the situation worse. In my experience, it's a matter of time until this type of setup becomes an issue rather an a feature.
