Game freezing during ride

We have been using Zwift for about 2 weeks now and have had a few issues with the ride freezing with the the result of not being able to resume or save the ride. If I check on the companion app it shows as I am still zwifting but this eventually disappears and I loose the record. Any ideas?

Please post up full details of your setup, including the specs of what you’re running Zwift on.

Here’s where I admit to not being techy. The tracker I have is a Tacx Flux S Trainer. My laptop uses Windows 11 and the companion app is on my android phone
