As someone who knows many people who were high-quality Spanish speaking elementary teachers in Texas, it's hard to find skilled and qualified people willing to work at that level working for the wages being offered when the cost of living is what it is and other jobs are offering considerably more.
When you can have 80% of the take home apay but have fewer parents issuing death threats while filling tacos at Taco Bell (and they pay for your community college to go elsewhere) it's no surprise teachers choose to go elsewhere.
Practically every school district in Texas is facing a qualified teacher shortage.
There is an issue around a general teacher shortage, mostly due to poor pay and treatment. It's hard to find teachers in general. It's been exacerbated recently in states like Texas, with proposed book bans and bans on teaching history. No one wants to get punished for assigning Brave New World or teaching about slavery (and teachers don't want to lie to kids about history, either).
Of course, the Trump admin has responded to this by deciding not to fund the TQP grant program, which in part trains and places teachers in high-need areas like STEM, special ed, and bilingual ed. This struggle is mostly a self-inflicted policy choice.
