Question: dsolve hangs on an ODE in Maple 2020.2 but not in 2019.2

There is a problem here somewhere. Maple hangs on this ODE. Looking at trace, it hangs in trying homogeneous G

is this a known defect and could be resolved?

restart;
infolevel[dsolve]:=4;
dsolve(x^3*diff(y(x),x)^2+x*diff(y(x),x)-y(x) = 0,y(x))

... hangs

Adding different timelimits, it looks like the function gcd/LinZip is the culprit. Since it always seems to be there each time the timelimit expires (if it expires, sometimes it hangs even with timelimit).  But I noticed the above function many times in timelimit. So it seems the above functions is what causes many of the hangs I see.

Using `Lie` method, dsolved finishes almost instantly.

restart;
dsolve(x^3*diff(y(x),x)^2+x*diff(y(x),x)-y(x) = 0,y(x),'Lie')

This is on Maple 2020.2

It would be useful to know the cause of the hang, as fixing it could solve other problems.

I also notice that on Maple 2019.2 the first example above finished very fast also. So this is an issue that was introduced in Maple 2020.
