only a few old RVX versions work without crashing on start

[ydqsbfsyi]

I've been using RVX v19.16.39 for months, and all of a sudden, in recent days, there's a bug: each video will stop at exactly 1 minute and stuck trying to load. This happened for many people, not just this version or just patched by Revancify. The usual answer is to patch a new version.

So I tried to patch another version. Just like months before, all the v20.* versions I tried, after installing, crash on start (I could only see the top "youtube" then app closed).
Fortunately there's an old version 19.17.42 inside Revancify's list, I tried that and it works.

Could anybody please help me with two questions:
1, why all RVX v20.* crash on start? and not every v19 works for me, either...... my phone is Android 10.
2, today I updated Revancify itself, as well as "update assets", and I find in the youtube list from apkmirror.com, old versions don't show, only one v19 is mixed up in the list. Is there any way to show more old versions, or I have to download some old stock version and "import"?

Same issue here, I'm currently using 19.47.53 I downloaded manually.
