It seems this change to ethers-rs is the cause

Add Location To Solidity Pragma Directive (#638)

add loc to pragma directive

PragmaDirective(Loc, Vec<DocComment>, Identifier, StringLiteral),

---

Here is a short term fix, until foundry guys release an official fix

1. Open ethers-solc resolver for current install

/Users/$USER/.cargo/git/checkouts/ethers-rs-c3a7c0a0ae0fe6be/93878e4/ethers-solc/src/resolver.rs

2. Change Line 426:

   SourceUnitPart::PragmaDirective(_, pragma, value) => {

   to

   SourceUnitPart::PragmaDirective(_, _, pragma, value) => {

3. Run cast install command

   cargo install --git https://github.com/gakonst/foundry --bin cast

there was a breaking change on solang-parser

fixed on ethers-rs here, https://github.com/gakonst/ethers-rs/pull/796

then needs a cargo update -p ethers here
