Last few rides have crashed

Ever since I got the Feb 23 update, my rides have crashed. Both crashed after at least 1 hour of riding. The first time crashed almost exactly at one hour. Last night crashed at an hour and 25 minutes I think.

What happens is the screen freezes and no more sound. The pc eventually gives me a message asking if I want to wait or close the program since it’s not responding.

Anyone else have this issue? I sent crash logs to Zwift and crickets.

Please tell us your entire set up, and the specs on your PC.

I run a Microsoft surface.
16gb ram, 15.5 useable
i7 1.3 to 1.5 GHz

Windows 10
950 gb HDD
895 gb free

I only use this for Zoom, and Zwift
