Error on formatting document: Could Not Load Type

esassaman

Visual Studio 2026 Version 18.3.2 (Feb 2026 feature update) and PHP Tools 1.88.18481, both the latest releases as of today.

Getting a popup messagebox Could Not Load Type 'Microsoft.WebTools.Languages.Css.Utilities.SortedRangeList`1' when I attempt to format the entire document (Ctrl+K, Ctrl+D).

This is the entire php file, just these two lines:
<?php ?>
<style></style>

If you remove either line, the error goes away.

I tried clearing my VS component cache, no love.

Any ideas? Are there logs somewhere that would be helpful?

I am not exactly sure then this problem started. I think it might have been after a recent VS update??
