Slider Revolution Issue with WP 5.5.

Hello,
After updating WP, plugins and theme to the latest versions available, all the sliders created with Slider Revolution are gone and the pages are blank where the sliders should be.
A warning message says: If you updated to WP 5.5. please don’t save any project in Slider Revolution (…) until updating to version 6.2.18.
Unfortunately, the version I’ve just downloaded from your server is 6.2.17.
Can this be the reason why the sliders don’t work? Can you guys make the latest version available asap?
Many thanks for your help and your much appreciated hard work.
