Valorant Crashing

For about 4 months now (or whenever they removed reyna for fixes) my valorant suddenly started crashing after 3-5 minutes. Some days it’ll work and some days it wont. And its not giving me an error its straight up crashing my entire pc. I’ve tried almost everything i could find to try and fix it but nothing works. I contacted Val support and they were no help. Sometimes when it crashes i get blue screened. Lmk if you need any other info
