Last session, I allowed a spell from Xanathar's that seems overpowered. While I tend to be a DM who likes to say yes to his players, I can detect that this one will upset the balance of the game. (I didn't do my due diligence and research that the spell has an OP reputation before the game, because I tend to err on the side of allowing official, published content.)
How do other DM's deal with these situations? Forbid the spell? Make changes to the spell to bring the power level to a reasonable level? increase the difficulty of encounters?

You're the judge.
Ideally the PCs should succeed and your job is to make it fun.
You control everything behind the screen.
Hit points, mobs, damage...
If the players like to be refreshed after every encounter, make each encounter that much more interesting.
Its not a video game.
The DM's job is not to make it fun. That's everyone's job.
If 1 spell fundamentally changes the game then it is reasonable to say that the spell is overpowered. Some spells are designed that way to give D&D a certain flavour. Fly, teleport, plane shift, etc.
Some aren't. Some tables don't want a level 2 spell to give each party member 35hp. Just because WotC published it in a book doesn't mean that a table's game needs to adapt to it.
Like you said, 'it's not a video game'. People aren't bound by what is published.
We'll have to agree to disagree...
I've been at plenty of tables with bad judges and it's incredibly hard to have a good time even with a known group of fun players with a bad judge.
One or two bad players can be countered with a good judge and the table has fun.

but aside from that, apart from a few level 9 spells, I have never experienced a spell completely ruining a game or campaign that a judge can't work around...this is all about imagination. A good judge just doesn't read from a book or a tablet and regurgitation the adventure; he/she embellishes, adds or subtracts and draws the players in. What does it matter if the players have 35 more hp...so do the monsters. They fly; pull them into aerial combats. One player has the "I win button", separate him from the group and see what happens.
