Find function in Trados Studio 2022 not working properly

For the last 6 months or so, I have noticed that the Find function in TS2022 (SR2 - 17.2.11.19134) is faulty. 'Find complete: no matches found.' pops up even though there are more matches. I have found that if I go to the top segment and press Find once more, more matches appear, and this cycle can be repeated several times in one document. It is a huge and time-consuming problem that the Find function cannot be trusted. I have been hoping for a fix, but that does not seem to be happening. Is anyone else experiencing this, and is there any hope for a fix? Thanks.
