Switching OS is like getting a new car.
But if you keep using the old car for work and new car for leisure you will not get used to the new car - you will not learn where the switches and knobs are and you will get frustrated everytime you use the new car.
Give the old car away or sell it - then you can concentrate on the new car.
Been there done that. When I got retired in 2014 - I skipped Windows completely and concentrated on Linux. The days were Windows were my primary operating system are gone.
Despite beeing retired - I have a paid parttime job as developer for an old friends business.
As part of this I still use a Windows Virtual Machine and Visual Studio 2022.
