Code execution is orders of magnitude slower than my previous version despite no changes to the code.

Type: Performance Issue

I updated from v1.130 to v1.132 and my cpu is now at maximum capacity and the same code takes several times longer to execute than it did before the update even though there have been no changes to the code. I've tried disabling unnecessary extensions and it has not made a difference.

VS Code version: Code 1.132.0 (df53daabb18cd157bdb08c7f01c34df936cf12f4, 2026-08-04T15:30:20Z)
