Strangely, it works when done correctly via limit:
f[a_] = Assuming[0 < a < 1,
Integrate[(x^2 Log[1 - x^4])/(1 + x^4), {x, 0, a}]];
A = Limit[f[a], a -> 1, Direction -> "FromBelow"];

The integration with help of Rubi gives after inserting the limits:
(1/(4*Sqrt[2]))*(Pi*Log[2] - Log[(Sqrt[2] + 1)^2]*Log[2] +

It is a known bug. Unfortunately, there is no way to change the current behavior.

I was able to find this workaround, I know not what it does.
In[1]:= Pause[3];(*abortable*)
Out[1]= $Aborted
In[2]:= Quiet@NotebookEvaluate@"abc";
In[3]:= Pause[3];(*unabortable*)
In[4]:= MathLink`LinkAddInterruptMessageHandler[$ParentLink]
In[5]:= Pause[3];(*Aborts are back!*)
Out[5]= $Aborted

I'm running Mathematica 12.2 on Windows and get the same, incorrect characters. I also noticed the \langle and \rangle are not rendering correctly, either.

cd = CategoricalDistribution[{{"Rain", "Fair"}, {"Win", "Lose"}},
{{0.4, 0.4}, {0.12, 0.08}}];
Update: Again using simple queries we can get two tables of conditional probabilities as Dataset objects
probtable = Information[cd, "ProbabilityTable"];
condProbResultGivenWeather = probtable[All, Normalize[#, ...

I think your syntax is just fine. Probability just doesn't know how to do it.
The brute force way, of course, is the following:
cd = CategoricalDistribution[{{"Rain", "Fair"}, {"Win", "Lose"}}, {{0.4, 0.4}, {0.12, 0.08}}];
Probability[result == "Win" && weather == "Fair", {weather, result} \...

This is obviously a subtle bug.
Thanks to @J.M.'sennui's hint there is a (slower) workaround.
A solution is to FunctionExpand the ParabolicCylinderD before taking the Asymptotic
tt1 = Asymptotic[
s1 = ParabolicCylinderD[-(1/2) - I/2, (-1 + I) x] //
FunctionExpand, x ->\[Infinity]] // FunctionExpand //
FullSimplify;
Then after the plot

I think this looks like a bug, though I have no authority to declare it. In particular, this looks like a hot mess:
That's the following:
tz = Entity["TimeZone", "America/Chicago"]
With[{t = DateObject[{2007, 11, 4, 1, 0, 0}, TimeZone -> tz]},
{t, UnixTime[t]}]
{ DateObject[{2007, 11, 4, 1, 0, 0}, "Instant", "...

The bug had been fixed. Here we attach the result.

This is certainly a bug: All pairs {a:(_String|_List), b_?(NumberQ[N@#]&)} that appear anywhere in epilog/prolog are replaced with {AbsoluteTime[a], b}.
An example that shows various cases that trigger the mysterious behavior as well as possible work-arounds:
epilog2 = Inset[Framed[
Grid[{{"FOO", 1.5},
{"FOO", BAR[1.5]},

I contacted Wolfram support and got the following answer.
I have forwarded an issue report to our Cloud development team. We hope this can be resolved in the future versions of Wolfram Cloud.
So that is not working in Wolfram 12.2.0.0.
